6 Amplifiers

Texas Instruments (TI) offers a wide range ofop amp types including high precision,microPower, low voltage, high voltage, highspeed and rail-to-rail in several differentprocess technologies. TI has developed theindustry's largest selection of low-power andlow-voltage op amps with features designedto satisfy a very wide range of applications.To help facilitate the selection process, aninteractive online op amp parametric searchengine is available at amplifier.ti.com/searchwith links to all op amp specifications.

Design Considerations

Choosing the best op amp for an applicationinvolves consideration of a variety of inter-related requirements. In doing so, designersmust often consider conflicting size, cost andperformance objectives. Even experiencedengineers can find the task daunting, but itneed not be so. Keeping in mind the followingissues, the choices can quickly be narrowedto a manageable few.

Supply voltage (VS)—tables include low voltage (< 2.7V min) and wide voltage range(> 5V min) sections. Other op amp selectioncriteria (e.g., precision) can be quickly exam-ined in the supply range column for anappropriate choice. Applications operatingfrom a single power supply may require rail-to-rail performance and consideration of precision-related parameters.

Precision—primarily associated with inputoffset voltage (VOS) and its change withrespect to temperature drift, PSRR andCMRR. It is generally used to describe opamps with low input offset voltage and lowinput offset voltage temperature drift.Precision op amps are required when amplifying tiny signals from thermocouplesand other low-level sensors. High-gain ormulti-stage circuits may require low offset voltage.

Gain bandwidth product (GBW)—the gainbandwidth of a voltage-feedback op ampdetermines its useful bandwidth in an application. The maximum available bandwidthis approximately equal to the gain bandwidthdivided by the closed-loop gain of the applica-tion. For voltage feedback amplifiers, GBW isa constant. Many applications benefit fromchoosing a much wider bandwidth/slew rate

op amp to achieve low distortion, excellentlinearity, good gain accuracy, gain flatness or other behavior that is influenced by feedback factors.

Power (IQ requirements)—a significant issuein many applications. Because op amps canhave a considerable impact on the overallsystem power budget, quiescent current,especially in battery-powered applications, is a key design consideration.

Rail-to-rail performance—rail-to-rail output provides maximum output voltageswing for widest dynamic range. This may beparticularly important with low operatingvoltage where signal swings are limited.Rail-to-rail input capability is often requiredto achieve maximum signal swing in buffer(G = 1) single-supply applications. It can beuseful in other applications, depending onamplifier gain and biasing considerations.

Voltage noise (VN)—amplifier-generatednoise may limit the ultimate dynamic range,accuracy or resolution of a system. Low-noise op amps can improve accuracy, even inslow DC measurements.

Input bias current (IB)—can create offseterror by reacting with source or feedbackimpedance. Applications with high sourceimpedance or high impedance feedback elements (such as transimpedance amplifiersor integrators) often require low input bias

current. FET-Input and CMOS op amps generally provide very low input bias current.

Slew rate—the maximum rate of change ofthe amplifier output. It is important whendriving large signals to high frequency. Theavailable large signal bandwidth of an opamp is determined by the slew rate SR/.707(2π)VP.

Package size—TI offers a wide variety ofmicroPackages, including WCSP, SOT23,SC70 and small, high power-dissipatingPowerPAD™ packages to meet space-sensitive and high-output drive requirements.Many TI single-channel op amps are available in SOT23, with some dual amplifiers in SOT23-8.

Shutdown mode—an enable/disable function that places the amp in a highimpedance state, reducing quiescent currentin many cases to less than 1µA. Allowsdesigners to use wide bandwidth op amps inlower power applications, enabling themonly when they are needed.

Decompensated amplifiers—for applications with gain greater than unitygain (G > 1), decompensated amps provide significantly higher bandwidth,improved slew rate and lower distortion overtheir unity-gain stable counterparts on thesame quiescent current or noise.

What is the amplitude of the input signal?To ensure signal errors are small relative tothe input signal, small input signals requirehigh precision (e.g., low offset voltage)amplifiers. Ensure that the amplified outputsignal stays within the amplifier output voltage.

Will the ambient temperature vary?Op amps are sensitive to temperaturevariations, so it is important to consideroffset voltage drift over temperature.

Does the common-mode voltage vary? Make sure the op amp is operated within its common-mode range and has anadequate common-mode rejection ratio

(CMRR). Common-mode voltage will induceadditional offset voltage.

Does the power supply voltage vary?Power supply variations affect the offset voltage. This may be especiallyimportant in battery-powered applications.

Common Op Amp Design Questions


Amplifiers 7

Technology Primer

Understanding the relative advantages ofbasic semiconductor technologies will help inselecting the proper device for a specificapplication.

CMOS Amps—when low voltage and/or lowpower consumption, excellent speed/power ratio,rail-to-rail performance, low cost and smallpackaging are primary design considerations,choose microPackaged CMOS amps boastingthe highest precision in the industry.

High-Speed Bipolar Amps—when the highestspeed at the lowest power is required, bipolartechnology delivers the best performance.Extremely good power gain gives very highoutput power and full power bandwidths onthe lowest quiescent power. Higher voltage requirements are also only satisfied in bipolartechnologies.

Precision Bipolar Amps—excel in limitingerrors relating to offset voltage. These ampsinclude low offset voltage and temperaturedrift, high open-loop gain and common-moderejection. Precision bipolar op amps are usedextensively in applications where the source

impedance is low, such as a thermocoupleamplifier, and where voltage errors, offsetvoltage and drift, are crucial to accuracy.

Low IB FET Amps—when input impedance isvery high, FET-input amps provide better over-all precision than bipolar-input amps becauseof very low input bias current. Using a bipolaramp in applications with high source imped-ance (e.g., 500MΩ pH probe), the offset, driftand noise produced by bias currents flowingthrough the source would render the circuitvirtually useless. When low current errors arerequired, FET amps provide extremely lowinput bias current, low offset current andhigh input impedance.

Dielectrically Isolated FET (Difet™) Amps—Difet processing enables the design ofextremely low input leakage amplifiers byeliminating the substrate junction diode present in junction isolated processes. Thistechnique yields very high-precision, low-noise op amps. Difet processes also minimizeparasitic capacitance and output transistor saturation effects, resulting in improvedbandwidth and wider output swing.

High-Speed Amplifiers

TI develops high-speed signal conditioningproducts using state-of-the-art processes thatgive leading-edge performance. Used in high-speed signal chains and analog-to-digitaldrive circuits, high-speed amps are broadlydefined as any amplifier having at least50MHz of bandwidth and at least 100V/µsslew rate. High-speed amps from TI come inseveral different types and supply voltage options.


Voltage-feedback type—the most commonly used amp and the basic buildingblock of most analog signal chains such asgain blocks, filtering, level shifting, buffering,etc. Most voltage-feedback amps are unity-gain stable, though some are decompensatedto provide wider bandwidth, faster slew rateand lower noise.

Current-feedback type—most commonly seen in video or DSL line driver applications, ordesigns where extremely fast slew rate is needed.

Fully differential amplifier (FDA)—the fullydifferential input and output topology has theprimary benefit of reducing even order harmonics, thereby reducing total harmonic distortion. The FDA also rejects common-modecomponents in the signal and provides a largeroutput swing to the load relative to single-ended amplifiers. Fully differential amplifiersare well-suited to driving analog-to-digital converters. A VCOM pin sets the output common-mode voltage required by newer, single-supply, ADCs.

FET-Input (or CMOS) amplifiers—have higherinput impedance than typical bipolar ampsand are more useful to interfacing to highimpedance sources, such as photodiodes intransimpedance circuits.

Video amplifiers—can be used in a number of different ways, but generally arein the signal path for amplifying, buffering,filtering or driving video lines. The specifica-tions of most interest are differential gainand differential phase. Current-feedbackamps are typically used in video applications,because of their combination of high slewrate and excellent output drive at low quiescent power.

Fixed and variable gain—these amps haveeither a fixed gain, or a variable gain that canbe set either digitally with a few control pins,or linearly with a control voltage. Fixed-gainamplifiers are fixed internally with gain setting resistors. Variable gain amplifiers canhave different gain ranges, and can also bedifferential input and/or output.

Packaging—high-speed amplifiers typicallycome in surface-mount packages, becauseparasitics of DIP packages can limit perform-ance. Industry standard surface-mount packages (SOIC, MSOP, TSSOP and QFN) handlethe highest speed requirements. For band-widths approaching 1GHz and higher, theQFN package decreases inductance andcapacitance.

Evaluation boards—high-speed amps have anassociated fully populated evaluation module(EVM) or an unpopulated printed circuit board(PCB). EVMs are a very important part of high-speed amplifier evaluation, since layout iscritical to design success. To make layout simple, Gerber files for the EVMs are available.See page 101 for more information.

OPA3875 functional block diagram.

Key Features• Small-signal bandwidth: 700MHz (AV =+2)• Bandwidth: 425MHz, 4VPP • Gain flatness: 0.1dB to 200MHz• Channel switching time: 4ns• Switching glitch: 40mVPP • Slew rate: 3100V/µs • Gain accuracy: 2.0V/V ±0.4% • 0.025%/0.025° differential gain/phase• Packaging: SO-8 or MSOP-8

(OPA875) or SSOP-16 (OPA3875)

Applications• RGB or Y/Pb/Pr video switching• Analog routing switcher • LCD projector input select• High resolution monitors• Broadcast video processing• Triple high speed ADC input mux

The OPA875 and OPA3875 are high-speed, very wideband, single-channel and triple-channel, 2:1 multiplexers. Gain accuracy and switching glitch of 40mVPP are improved over earlier solutions using anew (patented) input stage switching approach. System power may be optimized using the enable feature for the OPA3875. Using this, the OPA3875 powers down to a mere 0.9mA total supply current.The fixed gain-of-2 output stage is ideal for driving double terminated video loads directly. Where asingle channel of the OPA3875 is required, consider the OPA875.

rail-to-rail output that swings within 100mV ofthe rails to allow for either AC or DC-coupling.The THS7347 incorporates a 500MHz band-width, 1200V/µs unity-gain buffer making itideal for driving ADCs and video decoders,where the THS7327 offers an integrated 5thorder Butterworth anti-aliasing filter on eachchannel. These filters improve image qualityby eliminating DAC images.

Portable Video— Successfully designing ahigh-performance video system into low voltage portable applications requires carefulattention to many details. Portable applications impose very challenging technicalrequirements beyond those required in typicalvideo applications and demand particulartrade-offs in performance, power consumption,printed circuit board space and cost. A DC-coupled solution with integrated gain, low-pass filter, level-shifter, and shutdownsolves these challenges while maintaininggood video performance and eliminates theneed for large, expensive discrete components.The standard definition (SDTV) THS7314 andhigh definition (HDTV) THS7316 easily meetthese trade-offs by maintaining outstandinglow-cost performance while the EDTV/SDTVline driver THS7318, with it’s small profilewafer scale package, is ideal for extremelyboard space sensitive applications.

The new low power THS7315 is a fully-integrated SDTV video amplifier which featuresa rail-to-rail output stage allowing for both ACand DC line driving. The low 15.6mA quiescentcurrent at 3.3V makes it an excellent choice forUSB powered or other power sensitive videoapplications.

Video amplifiers—can be used in a numberof different ways, but generally are in the signal path for amplifying, buffering, filtering ordriving video lines. The specifications of mostinterest for composite video signals, or CVBS,are differential gain and differential phase. Forother video signals, such as Y’P’bP’r or RGB,bandwidth – both small signal and large signal, and slew rate are of most importance.Noise and DC accuracy is also consideredimportant in some high-end applications.

The traditional Voltage-Feedback (VFB) ampli-fiers are widely used because of their ability tobe configured for almost any situation. ManyVFB amplifiers have the ability to accept inputsignals going to the negative rail (or ground),allowing use in many single-supply systems.Additionally, many VFB amplifiers offer rail-to-rail outputs offering the widest dynamic rangepossible on small supplies. Traditional VFBamplifiers (non-RRO) designed for video offerthe ability to have very high slew rates, widebandwidths, low noise, and very good DC characteristics. Current-feedback amps arecommonly found in high-end video applications,because of their combination of high slew rateand excellent output drive at low quiescent power.

High-Speed Video Multiplexers—Numerous video applications, such as RGB orYPbPr video switching, video routers, high resolution monitors, etc. are creating anincreased need for high-speed switching withmultiplexers (muxes). With the increased needto reduce board space are also the demandsthat these muxes provide low power consumption as well as increased functionality,such as the ability to drive 75-Ohms or 150-Ohms while maintaining good video

performance specifications. These specifications include low crosstalk, fast settling, gain flatness, low switching glitchalong with low differential gain and differentialphase. The new OPA875 and OPA3875 single-and triple 2:1 multiplexers along with the newOPA4872, 4:1 multiplexer easily meets theserequirements. Using a new patented inputstage switching approach, the switching glitchis much improved over earlier solutions. Thistechnique uses current steering as the inputswitch while maintaining an overall closed-loop design.

TI brought new technology to the market withthe introduction of the THS7303, THS7313 andTHS7353. These three-channel devices werethe first to offer full I2C programmability of allfunctions independently for each channel,which provides the designer the flexibility toconfigure a video system as required or on-the-fly, without the need for hardware upgrades ormodifications. The devices are designed withintegrated Butterworth filters to provide all theanalog signal conditioning required in videoapplications such as set-top boxes, digital televisions, personal video recorders/DVDreaders and portable USB devices. These highlyintegrated devices provide space savings as aresult of the high levels of integration andadvanced package technology.

The strong combination of integrated featuresand optimized design make TI’s THS7327 andnew THS7347, well suited for use in projectorsand professional video systems. Both 3-channel RGBHV video buffers offer a monitorpass-thru amplifier, unity gain buffer, 2:1 inputmux, I2C control of all functions on each channel, HV synch paths with AdjustableSchmitt Trigger, selectable bias modes and

Comparators

Comparator ICs are specialized op ampsdesigned to compare two input voltages andprovide a logic state output. They can beconsidered one-bit analog-to-digitalconverters.

The TI comparator portfolio consists of a variety of products with various performancecharacteristics, including: fast ns responsetime, wide input voltage ranges, extremelylow quiescent current consumption and opamp and comparator combination ICs.

Comparator vs. Op AmpComparator Op Amp

Speed (Response time) Yes NoLogic Output Yes NoWide Diff. Input Range Yes YesLow Offset Drift No Yes

In general, if a fast response time is required,use a comparator.

Design ConsiderationsOutput topology• Open collector—connects to the logic

supply through a pull-up resistor and allows comparators to interface to a variety of logic families.

• Push-pull—does not require a pull-up resistor. Because the output swings rail-to-rail, the logic level is dependent on the voltage supplies of the comparator.

Response time (propagation delay)—applications requiring “near real-time” signal response should consider comparatorswith nanosecond (ns) propagation delay. Notethat as propagation delay decreases, supply current increases. Evaluate what mix of performance and power can be afforded. TheTLV349x family offers a unique combinationof speed/power with 5µs propagation delayon only 1µA of quiescent current.

Combination comparator and op amp—forinput signals requiring DC level shifting and/or

gain prior to the comparator, consider theTLV230x (open drain) or TLV270x (push-pull) opamp and comparator combinations. These dualfunction devices save space and cost.

Comparator and voltage reference—comparators typically require a referencevoltage to compare against. The TLV3011 is an integrated comparator and voltage reference combination in a space-savingSC70 package.

Difference Amplifiers

Common-mode input voltage range—selection of the most suitable difference ampbegins with an understanding of the inputvoltage range. Some offer resistor networksthat divide down the input voltages, allowing operation with input signals that exceed thepower supplies. A five-resistor version of thesimple difference amplifier results in a devicethat can operate with very high levels ofcommon-mode voltage—far beyond the supply rails.

Gain—signal amplification needed for thedesired circuit function must be considered.With the uncommitted on-chip op amp, theINA145 and the INA146 can be configured forgains of 0.1 to 1000.

Sensor impedance—should be <0.001 of difference amp input impedance to retainCMR and gain accuracy. In other words, theamp input impedance should be 1,000 timeshigher than the source impedance.

Offset voltage drift (µV/°C)—input offsetvoltage changes over temperature. This ismore critical in applications with changingambient temperature.

Quiescent current—often of high importancein battery-powered applications, whereamplifier power consumption can greatlyinfluence battery life.

Slew rate—if the signal is reporting a temperature, force or pressure, slew rate isnot generally of great concern. If the signal is for an electronic event, (e.g., current, power output) a fast transition maybe needed.

Common-mode rejection—a measure ofunwanted signal rejection and the amp's ability to extract a signal from surrounding DC,power line or other electrical noise.

The difference amplifier is a moderate inputimpedance, closed-loop, fixed-gain block thatallows the acquisition of signals in the presence of ground loops and noise. Thesedevices can be used in a variety of precision,general-purpose, audio, low-power, high-speed and high-common-mode voltage applications.

Difference Amplifier

The basic difference amplifier employs an opamp and four on-chip, precision, laser trimmedresistors. The INA132, for example, operateson 2.7V to 36V supplies and consumes only160µA. It has a differential gain of 1 and high common-mode rejection. The output signalcan be offset by applying a voltage to the Refpin. The output sense pin can be connecteddirectly at the load to reduce gain error.Because the resistor network divides downthe input voltages, difference amplifiers canoperate with input signals that exceed thepower supplies.

High Common-Mode VoltageDifference Amplifier Topology

A five-resistor version of the simple difference amplifier results in a device thatcan operate with very high levels of common-mode voltage—far beyond itspower supply rails. For example, the INA117can sense differential signals in the presenceof common-mode voltages as high as ±200Vwhile being powered from ±15V. This deviceis very useful in measuring current from ahigh-voltage power supply through a high-side shunt resistor.


Power supply—common-mode voltage isalways a function of the supply voltage. TheINA103 instrumentation amplifier is designedto operate on voltage supplies up to ±25V,while the INA122 difference amp can beoperated from a 2.2V supply.

Output voltage swing—lower supply voltage often drives the need to maximizedynamic range by swinging close to the rails.

Should I Use a Difference Amplifier or Instrumentation Amplifier?

Difference amplifiers excel when measuring signals with common-mode voltages greaterthan the power supply rails, when there is a low power requirement, when a small packageis needed, when the source impedance is low or when a low-cost differential amp isrequired. The difference amp is a building block of the instrumentation amp.

Instrumentation amplifiers are designed to amplify low-level differential signals where the maximum common-mode voltage is within the supply rails. Generally, using an adjustablegain block, they are well-suited to single-supply applications. The three-op-amp topologyworks well down to Gain = 1, with a performance advantage in AC CMR. The two-op-amptopology is appropriate for tasks requiring a small package footprint and a gain of 5 orgreater. It is the best choice for low-voltage, single-supply applications.

Analog Current Shunt Monitors

Current shunt monitors are a unique class ofhigh common-mode voltage difference amplifiers that have the ability to operate onsingle, low-voltage supplies.

Current shunt monitors have a common-modevoltage range that is independent of powersupply (as opposed to classical difference amplifiers where the common-modevoltage range is proportional to power supply voltage). Unlike most high common-mode voltage difference amplifiers, currentsense shunt monitors have gains for sensinglow differential voltages (50mV to 100mV).

Current sensing can be done on either thelow-side (ground) or high-side (power supply). Low-side sensing is simple andrequires no special components, but it oftencannot be used because it either disturbsground or requires additional wiring. Currentshunt monitors are intended to make it easyto implement high-side current sensing.Discrete solutions to high-side sensing aredifficult and costly to implement.

Common-Mode VoltageThe common-mode voltage range is typicallythe first parameter to be considered and thisbreaks down into two basic categories of current shunt monitors: families that handleonly positive common-mode voltages above+2.7V (with a choice of upper limits up to+60V); and a family that handles –16V to +80V.The ability to sense common-mode voltages atground and below is required when the powersupply that the current is being sensed fromcould get shorted out, or if the shunt resistor isin an inductive load that could be exposed toinductive kickback. In addition, a common-mode range to –16V allows the current shuntmonitor to be used to sense current in –12V to –15V power supplies. Lastly, it easily withstands battery reversals in 12V automotive applications.

Current Output vs. Voltage OutputAnother broad category is the type of output.The current output families enable the gainto be set by selecting the value of an externalload resistor. The fastest current shunt monitor is the INA139 or INA169. Current output INA170, and current output deviceshave a minimum common-mode voltage of+2.7V, with a maximum up to +60V.

Voltage output current shunt monitors havethe advantage of a buffered voltage outputwhich eliminates the need for an additionalop amp in many applications. These devicesare available in fixed gains of 14, 20, 50 and100. The voltage output current shunt monitors all have a common-mode range of–16V to +80V.

The instrumentation amplifier (IA) is a highinput impedance, closed-loop, fixed- oradjustable-gain block that allows for theamplification of low-level signals in the presence of common-mode errors and noise.TI offers many types of instrumentationamplifiers including single-supply, low-power,high-speed and low-noise devices. Theseinstrumentation amplifiers are available ineither the traditional three-op-amp or in the cost-effective two-op-amp topology.

Three-Op-Amp Version

The three-op-amp topology is the benchmarkfor instrumentation amplifier performance.These devices provide a wide gain range(down to G = 1) and generally offer the highestperformance. Symmetrical inverting and non-inverting gain paths provide better common-mode rejection at high frequencies.Some types use current-feedback-type inputop amps which maintain excellent bandwidthin high gain.

Two-Op-Amp Version

The two-op-amp topology can provide widercommon-mode voltage range, especially inlow-voltage, single-supply applications. Theirsimpler internal circuitry allows lower cost,lower quiescent current and smaller packagesizes. This topology, however, does not lenditself to gains less than four (INA125) or five(all others).


Supply voltage—TI has developed a series oflow-voltage, single-supply, rail-to-rail instrumentation amps suitable for a widevariety of applications requiring maximumdynamic signal range.

Gain requirement—for high-gain applicationsconsider a low total noise device, becausedrift, input bias current and voltage offset allcontribute to error.

Common-mode voltage range—the voltageinput range over which the amplifier canoperate and the differential pair behaves as alinear amplifier for differential signals.

Input bias current—can be an important factor in many applications, especially thosesensing a low current or where the sensorimpedance is very high. The INA116 requiresonly 3fA typical of input bias current.

Offset voltage and drift—IAs are generally used in high-gain applications,where any amp errors are amplified by thecircuit gain. These errors can become signifi-cant unless VOS and drift performance areconsidered in the device selection. Bipolarinput stage INAs generally have smaller errorcontribution from offset and drift in lowsource impedance applications.

Current-feedback vs. voltage-feedback inputstage—appropriate for designers needinghigher bandwidth or a more consistent 3dBrolloff frequency over various gain settings.The INA128 and INA129 provide a significantly higher 3dB rolloff frequency than

voltage-feedback input stage instrumentationamps and have a 3dB rolloff at essentially thesame frequency in both G = 1 and G = 10 configurations.

Technical Information

IAs output the difference accurately betweenthe input signals providing Common-ModeRejection (CMR). It is the key parameter andmain purpose for using this type of device.CMR measures the device’s ability to rejectsignals that are common to both inputs.

IAs are often used to amplify the differentialoutput of a bridge sensor, amplifying the tinybridge output signals while rejecting thelarge common-mode voltage. They provideexcellent accuracy and performance, yetrequire minimal quiescent current. Gain isusually set with a single external resistor.

In some applications unwanted common-modesignals may be less conspicuous. Real-worldground interconnections are not perfect.What may, at first, seem to be a viable single-ended amplifier application canbecome an accumulation of errors. Error voltages caused by currents flowing inground loops sum with the desired input signal and are amplified by a single-endedinput amp. Even very low impedance groundscan have induced voltages from stray magnetic fields. As accuracy requirementsincrease, it becomes more difficult to designaccurate circuits with a single-ended inputamplifier. The differential input instrumentationamplifier is the answer.

• Wide output swing: within 10mV of rails• Single supply range: +2.7V to +5.5V• Temp range: –40°C to +85°C• Packaging: MSOP-8, MSOP-10

Applications• Low-level transducer amplifier for

bridges, load cells, thermocouples• Wide dynamic range sensor

measurements• High-resolution test systems• Weigh scales• Multi-channel data acquisition systems• Medical instrumentation

The INA326 uses a new, unique internal circuit topology that provides true rail-to-rail input. Unlikeother instrumentation amplifiers, it can linearly process inputs to 20mV below the negative powersupply rail, and 100mV above the positive power supply rail. Conventional instrumentation amplifierinput topologies cannot deliver such wide dynamic performance.

In most instrumentation amplifiers, the ability to reject common-mode signals is derived through acombination of input amplifier CMR and accurately matched resistor ratios. The INA326 converts theinput voltage to a current, allowing the input amplifiers to accurately match and reject common-modeinput voltage and power supply variation without the use of resistors.

Programmable Gain Amplifiers

Programmable gain instrumentationamplifiers (PGAs) are extremely versatiledata acquisition input amplifiers that provide digital control of gain forimproved accuracy and extended dynamicrange. Many have inputs that are protectedto ±40V even with the power supply off.A single input amplifier type can be connected to a variety of sensors or signals. Under processor control, theswitched gain extends the dynamic rangeof the system.

All PGA-series amps have TTL- or CMOS-compatible inputs for easy microprocessorinterface. Inputs are laser trimmed forlow offset voltage and low drift to allowuse without the need of external components.

Design ConsiderationsPrimary

Digitally-selected gain required—twopins allow the selection of up to four different gain states. A PGA202 andPGA203 can be put in series for greatergain selection.

Non-linearity (accuracy)—depends heavilyon what is being driven. A 16-bit converterwill require significantly better accuracy(i.e., lower non-linearity) than a 10-bitconverter.

Secondary

Gain error and drift—for higher gain,high-precision applications will requirecloser attention to drift and gain error.

Input bias current— high source impedanceapplications often require FET-input ampsto minimize bias current errors.


The PGA206 provides binary gain steps of1, 2, 4 and 8V/V, selected by CMOS- orTTL-compatible inputs. The PGA207 hasgains of 1, 2, 5 and 10V/V, adding a fulldecade to the system dynamic range. Thelow input bias current, FET-input stageassures that series resistance of the multiplexer does not introduce errors.Fast settling time (3.5µs to 0.01%) allowsfast polling of many channels.

The PGA204 and PGA205 have precisionbipolar input stages especially well suited to low-level signals. The PGA205has gain steps of 1, 2, 4 and 8.

Consumers are enjoying new ways to listen to music, books and news, whiledemanding more flexibility, better quality andmultifunctional products. There is an ever-increasing demand for high-end entertainment for the everyday consumer.The market expects the best listening experience from any audio format and source, mobile or stationary and at a competitive price.

By offering flexible, cost-efficient, end-to-end audio solutions, TI provides OEMsand ODMs with faster time-to-market andone-stop shopping. TI's complete audio solutions include best-in-class silicon, systems expertise, software and support. Byleveraging the programmability, performanceheadroom and design flexibility of TI's leadingDSP and analog technologies, customershave the ability to build audio products withmore functionality that offer a true, lifelikesound experience at a lower overall system cost.


PrimaryOutput power—supply voltage and loadimpedance limit the level of output power(i.e., volume) an audio power amp (APA) candrive. Always verify that the desired outputpower is theoretically possible with the equation: where VO is the RMS voltage of theoutput signal and RL is the load impedance.

Output configuration—there are two types ofoutput configurations, single-ended (SE) andbridge-tied load (BTL). An SE configuration iswhere one end of the load is connected tothe APA and the other end of the load is connected to ground. Used primarily in headphone applications or where the audiopower amplifier and speaker are in differentenclosures. A BTL configuration is whereboth ends of the load are connected to anAPA. This configuration effectively quadruplesthe output power capability of the system

and is used primarily in applications that arespace constrained and where the APA andspeaker are in the same enclosure.

Total Harmonic Distortion + Noise (THD+N)—harmonic distortion is distortion at frequen-cies that are whole number multiples of thetest tone frequency. THD+N is typically specified for rated output power at 1kHz.Values below 0.5 percent to 0.3 percent are negligible to the untrained ear.

Amplifier technology (Class-D and Class-AB)—Class-D and Class-AB are the most commonAPAs in consumer electronics, because oftheir great performance and low cost. Class-Damps are very efficient and provide thelongest battery life and lowest heat dissipation. Class-AB amps offer the greatestselection of features (e.g., digital volume control and bass boost).

SecondaryDigital volume control—this input changesthe gain of the APA when digital high or lowpulses are applied to the UP and DOWN pinsof the device.

DC volume control—internal gain settings that are controlled by DC voltageapplied to the VOLUME pin of the IC.

Integrated gain settings—the internal gainsettings are controlled via the input pins,GAIN0 and GAIN1, of the IC.

DEPOP—circuitry internal to the APA. It minimizes voltage spikes when the APA turns on, off, or transitions in or out of shutdown mode.

MUX—allows two different audio sources tothe APA that are controlled independently ofthe amplifier configuration.

Shutdown—circuitry that places the APA in avery low power consumption standby state.

Technical InformationTI APAs are easy to design with, requiring onlya few external components.

Power supply capacitors—CVDDminimizes THD by filtering off the low frequency noise and the high frequency transients.

Input capacitors—in the typical application, CIN,is required to allow the amplifier to bias theinput signal to the proper dc level for opti-mum operation. CIN is usually in the 0.1µF to10µF range for good low-frequency response.

Bypass capacitor—CBYPASS controls the startup time and helps to reduce the THD.Typically, this capacitor is ten times largerthan the input decoupling capacitors (CIN).

Layout—by respecting basic rules, Class-Damplifiers layout can be made easy.Decoupling caps must be close to the device,the output loop must be small to avoid theuse of a filter and the differential input traces must be kept together to limit the RFrectification. Analog VDD and switching VDDneed to be separated back to supply source.

Migration path—APA products are in a constant evolution moving from Class-ABmono speaker drivers to optimized stereoClass-D amplifiers with advanced features. The latest generation is the mostcost effective for the application.

Power Amplifiers and Buffers

TI power amplifiers solve tough high-voltageand high-current design problems in applica-tions requiring up to 100V and 10A output current. Most are internally protected againstthermal and current overload, and some offeruser-defined current limiting. The unity-gainbuffer amplifier series provides slew rates upto 3600V/µs and output current to 250mA.

Design ConsiderationsPower dissipation—determines the appropriate package type as well as the sizeof the required heat sink. Always stay withinthe specified operating range to maintainreliability of the power amps. Some poweramps are internally protected against over-heating and overcurrent. The thermally-enhanced PowerPAD™ package providesgreater design flexibility and increased thermal efficiency in a standard size IC

package. PowerPAD provides an extremelylow thermal resistance path to a groundplane or special heatsink structure.

Full-power bandwidth—or large-signal band-width, high FPBW is achieved by using poweramps with high slew rate.

Current limit—be aware of the specified operating area, which defines the relationship between supply voltage and current output. Both power supply and loadmust be appropriately selected to avoidthermal and current limits.

Thermal shutdown—the incorporation ofinternal thermal sensing and shut-off willautomatically shut-off the amplifier shouldthe internal temperature reach a specifiedvalue.

Technical Information Power AmpsUnlike other designs using a power resistor in series with the output currentpath, the OPA547, OPA548 and OPA549power amps sense current internally. Thisallows the current limit to be adjusted fromnear 0A to the upper limit with a control signal or a low-power resistor. This feature isincluded in the OPA56x series. The new 2AOPA567 comes in the tiny QFN package.

BufferThe BUF634 can be used inside the feedback loop to increase output current,eliminate thermal feedback and improvecapacitive load drive. When connected insidethe feedback loop, the offset voltage andother errors are corrected by the feedback ofthe op amp.

Pulse Width Modulation Power Drivers

from a DAC, while the DRV592 accepts aPWM input signal.

Output filter—in some applications, a low-pass filter is placed between each output ofthe PWM driver and the load to remove theswitching frequency components. A second-order filter consisting of an inductor andcapacitor is commonly used, with the cut-offfrequency of the filter typically chosen to beat least an order of magnitude lower than theswitching frequency. For example, a DRV593switching at 500kHz can have a 15.9kHz cut-off frequency. The component values arecalculated using the following formula:

FC = 1 / [ 2 •π• (√(L • C) ) ]

The inductor value is typically chosen to beas large as possible, and is then used to calculate the required capacitor value for thedesired cut-off frequency.

TI’s pulse width modulation (PWM) powerdrivers are specifically designed for applica-tions requiring high current at low to moder-ately high voltages, ranging from 5V to 60V.Loads include electromechanical loads, suchas solenoids, coils, actuators, and relays, aswell as heaters, lamps, thermoelectric coolers and laser diode pumps.

These products feature integrated powertransistors, which save considerable circuit board area compared to discreteimplementations. Unlike the operation of linear drivers, PWM operation offers efficiencies as great as 90%, resulting in lesspower wasted as heat and reduced demandon the power supply. The DRV10x operatesfrom +8V to +60V and has a single low-sideor high-side power switch. The devices in theDRV59x family may be analog or digitallycontrolled and operate from 0% to 100%duty cycles. The DRV59x operates on +2.8Vto +5.5V and has internal H-bridge outputswitches in series with the load, allowing for bi-directional current flow from a singlepower supply.


Supply voltage—selection begins with thepower supply voltages available in the system. TI’s families of PWM power driversoperate from 2.8V to 5.5V for the DRV59x familyand from 2.8V to 60V for the DRV10x family.

Output current and output voltage—the loadto be connected to the power driver will also

help determine the proper PWM power driversolution. The maximum output currentrequired by the load should be known. Themaximum output voltage capability of thedriver may be calculated as follows:

VO (max) = VS – [ IO (max) • 2 • RDS(ON) ]

Efficiency—a lower on-resistance (RON) ofthe output power transistors will yieldgreater efficiency. Typically, RDS(ON) is specified per transistor. In an H-bridge outputconfiguration, two output transistors are inseries with the load. To quickly estimate theefficiency, use the following equation:

Efficiency = RL / [ RL + ( 2 • RDS(ON) ) ]

Analog or digital control—TI offers both H-bridge and single-sided drivers. TheDRV590, DRV591, DRV593 and DRV594 eachaccept a DC voltage input signal, either froman analog control loop (i.e., PID controller) or

LOG112 functional block diagram.

TI has achieved significant advancement inlog amp technology. The logarithmic amplifieris a versatile integrated circuit that computesthe logarithm of an input current relative to areference current or the log of the ratio oftwo input currents. Logarithmic amplifierscan compress an extremely wide inputdynamic range (up to 8 decades) into an easily measured output voltage. Accuratematched bipolar transistors provide excellentlogarithmic conformity over a wide input current range. On-chip compensation achievesaccurate scaling over a wide operating temperature range.

TI log amplifiers are designed for optical networking, photodiode signal compression,analog signal compression and logarithmic

computation for instrumentation. Some logamps, such as the LOG102, feature additionaluncommitted op amps for use in a variety offunctions including gain scaling, inverting, filtering, offsetting and level comparison todetect loss of signal. The LOG2112 is a dualversion of the LOG112 and includes two logamps, two uncommitted output amps and asingle shared internal voltage reference.

Design ConsiderationsOutput scaling—amplifier output is 0.32V, 0.5V or 1.0V per decade and is theequivalent of the gain setting in a voltageinput amp.

Quiescent current—lowest in LOG101 andLOG104.

Conformity error—measured with 1nA to1mA input current converted to 5V output.More than 16-bits of dynamic range areachievable.

Auxiliary op amps—some log amps haveadditional uncommitted op amps that can beused to offset and scale the output signal tosuit application requirements.

Technical InformationLog amplifiers provide a very wide dynamicrange (up to 160dB), extremely good DC accuracy and excellent performance over the full temperature range.

LOG112 Key Features• Easy-to-use complete function• Output scaling amplifier• On-chip 2.5V voltage reference• High accuracy: 0.2% FSO over 5 decades• Wide input dynamic range:

Integrating Amplifiers

Integrating amplifiers provide a precision,lower noise alternative to conventional transimpedance op amp circuits whichrequire a very high value feedback resistor.Designed to measure input currents over anextremely wide dynamic range, integratingamplifiers incorporate a FET op amp, integratingcapacitors, and low-leakage FET switches.Integrating low-level input current for a user-defined period, the resulting voltage is storedon the integrating capacitor, held for accuratemeasurement and then reset. Input leakageof the IVC102 is only 750fA. It can also measure bipolar input currents.

The ACF2101 two-channel integrator offersextremely low bias current, low noise, anextremely wide dynamic range and excellentchannel isolation. Included on each of the twointegrators are precision 100pF integrationcapacitors, hold and reset switches and output multiplexers. As a complete circuit ona chip, leakage current and noise pickuperrors are eliminated. An output capacitorcan be used in addition to (or instead of) theinternal capacitor depending on designrequirements.


Supply voltage—while single-supply operation is feasible, bipolar-supply operation is most common and will offer thebest performance in terms of precision anddynamic range.

Number of channels—IVC102 offers a singleintegrator, while the ACF2101 is a dual.

Integration direction—either into or out ofthe device. IVC102 is a bipolar input currentintegrator and will integrate both positiveand negative signals. ACF2101 is a unipolarcurrent integrator, with the output voltageintegrating negatively.

Input bias (leakage) current—often sets alower limit to the minimum detectable signalinput current. Leakage can be subtractedfrom measurements to achieve extremelylow-level current detection (<10fA). Circuitboard leakage currents can also degrade theminimum detectable signal.

Sampling rate and dynamic range—theswitched integrator is a sampled system controlled by the sampling frequency (fs),

which is usually dominated by the integration time. Input signals above theNyquist frequency (fs/2) create errors bybeing aliased into the sampling frequencybandwidth.


Although these devices use relatively slow op amps, they may be used to measure veryfast current pulses. Photodiode or sensorcapacitance can store a pulse charge temporarily, the charge is then slowly integrated during the next cycle.

See the OPT101 data sheet for monolithicphotodiode and transimpedance amplifier. TheOPT101 converts light directly into a voltageoutput, with low leakage current errors, minimal noise pick-up and low gain peakingdue to stray capacitance.

The ISO721 digital isolator is a logic input and output buffer separated by a silicon oxide (SiO2)insulation barrier that provides galvanic isolation of up to 4000V. Used in conjunction with isolated power supplies, the device prevents noise currents on a data bus or other circuits fromentering the local ground and interfering with or damaging sensitive circuitry.

A binary input signal is conditioned, translated to a balanced signal, then differentiated by thecapacitive isolation barrier. Across the isolation barrier, a differential comparator receives thelogic transition information, then sets or resets a flip-flop and the output circuit accordingly. Aperiodic update pulse is sent across the barrier to ensure the proper dc level of the output. Ifthis dc-refresh pulse is not received for more than 4µs, the input is assumed to be unpoweredor not functional and the fail-safe circuit drives the output to a logic high state.

There are many applications where it isdesirable, even essential, that a sensor nothave a direct (galvanic) electrical connectionwith the system to which it is supplying datain order to avoid either dangerous voltages orcurrents from one half of the system fromdamaging the other half. Such a system issaid to be "isolated", and the area whichpasses a signal without galvanic connectionsis known as an "isolation barrier".

Isolation barrier protection works in bothdirections, and may be needed in either halfof the system, sometimes both. Common applications requiring isolation protection are

those where sensors may accidentallyencounter high voltages and the system it isdriving must be protected. Or a sensor mayneed to be isolated from accidental high voltages arising downstream in order to protect its environment: examples includeprevention of explosive gas ignition causedby sparks at sensor locations or protectingpatients from electric shock by ECG, EEG andEMG test and monitoring equipment. TheECG application may require isolation barriersin both directions: the patient must be protected from the very high voltages(>7.5kV) applied by the defibrillator, and the

technician handling the device must be protected from unexpected feedback.

Applications for Isolation Amplifiers

• Sensor is at a high potential relative toother circuitry (or may become so underfault conditions)

• Sensor may not carry dangerous voltages,irrespective of faults in other circuitry (e.g.patient monitoring and intrinsically safe equipment for use with explosive gases)

• To break ground loops

Amplifiers for Driving Analog-to-Digital Converters

Data acquisition systems generally require anamplifier preceding the ADC to buffer theinput signal. Most modern ADCs possesscomplex input characteristics due to thecapacitive charging and switching that occurs during sampling and conversion. This behaviorcauses transient currents on the ADC’s inputthat can disturb or distort a precision analoginput signal. The input amplifier serves toprovide a stable, accurate signal in the presence of these current transients. It canalso provide gain (or attenuation), level shifting, filtering and other signal conditioning functions.

Selecting the input op amp requires attentionto many considerations. DC accuracy may narrow the possible choices of an amplifier.The amplifier must have sufficiently low offset voltage, offset voltage drift, input biascurrent, noise, and so forth, to meet therequired accuracy performance. It is often thedynamic performance characteristics, however,that prove most troublesome in the selectionprocess. The amplifier must preserve therequired dynamic signal characteristics.


Time domain issues—some applicationsdemand that the amplifier respond accuratelyto full-scale changes in input voltage. Forexample, a multiplexed-input system mayhave input voltages equal to full-scaleextremes on two adjacent inputs. The amplifierand ADC must respond to this sudden full-scale change in one sampling period.

Settling time—an all-encompassing specification used to describe the ability ofan amplifier to respond to a large change in

input voltage. The settling time includes thelarge-signal period determined by slew rateand the small-signal settling period determinedprimarily by the bandwidth of the amplifier.Slewing time varies with the step size.Though generally specified for a specific step size, the settling time for other stepsizes can be inferred from the slewing portion of the step.

The small-signal portion of the settling wave-form is affected by the gain of the inputamplifier. If the amplifier is placed in a highergain, system bandwidth is reduced, propor-tionally increasing the small-signal portion ofthe settling waveform.

Frequency domain performance—many ADCsare used to digitize dynamic waveforms suchas audio. Rapid full-scale signal steps arerarely, if ever, encountered in these systems.For this reason, such systems generally specify spectral purity of the digitized signal.The amplifier must support this applicationwith the required distortion performance.Many amplifiers specify THD+N (total harmonic distortion + noise). Other measures arealso used. All these measures are made byapplying a pure sine wave (or combination ofsine waves) and measuring the spectral content in the amplifier's output that are not present in its input signal.


The input amplifier is generally connected tothe ADC through an R-C network. Thoughoften called a filter, this network actuallyserves as a "flywheel" in the presence of thecurrent pulses created by the ADC's input circuitry. The circuit values of this circuitdepend on both the amplifier and the ADCcharacteristics and often must be optimizedfor a particular application. The optimumcapacitor value is generally in the range of 10to 50 times the input capacitance of the ADC.The resistor is chosen to meet the speed orbandwidth requirement of the application.

The op amps shown in the following tableare among the most likely choices for theindicated conversion speeds and ADC architectures. Depending on specific application requirements, other amplifiersmay provide improved performance.

52 ADCs by Architecture

Delta-Sigma (∆Σ) ADCs

Delta-sigma converters are capable of veryhigh resolution, and are ideal for convertingsignals over a very wide range of frequenciesfrom DC to several megahertz. In a delta-sigma ADC, the input signal is oversampled bya modulator, then filtered and decimated by adigital filter producing a high-resolution datastream at a lower sampling rate.

The delta-sigma architecture approachallows resolution to be traded for speed andboth to be traded for power. This nearly continuous relationship between data rate,resolution and power consumption makesdelta-sigma converters extraordinarily flexible.In many delta-sigma converters, this relationship is programmable, allowing a single device to handle multiple measurement requirements.

Because delta-sigma converters oversampletheir inputs, they can perform most anti-aliasing filtering in the digital domain.Modern VLSI design techniques havebrought the cost of complex digital filters farbelow the cost of their analog equivalents.Formerly unusual functions, such as simultaneous 50Hz and 60Hz notch filtering,are now built into many delta-sigma ADCs.

Typical high-resolution applications for delta-sigma ADCs include audio, industrialprocess control, analytical and test instrumentation and medical instrumentation.

Recent innovations in ADC architectureshave led to a new class of ADC architecturewhich uses both the pipeline and the oversampling principle.These, very high-speedconverters push the data rates into the MSPSrange, while maintaining resolutions of 16-bits and higher.These speeds enable ahost of new wide bandwidth signal processingapplications such as communications andmedical imaging.

Most delta-sigma ADCs have inherently differential inputs. They measure the actualdifference between two voltages, instead ofthe difference between one voltage andground. The differential input structure of adelta-sigma makes it ideal for measuring

differential sources such as bridge sensorsand thermocouples. Frequently, no inputamplifiers are required for these applications.

Delta-sigma converters work differently thanSAR converters. A SAR takes a "snapshot" ofan input voltage and analyzes it to determinethe corresponding digital code. A delta-sigmameasures the input signal for a certain period of time and outputs a digital code corresponding to the signal's average overthat time. It is important to remember theway delta-sigma converters operate, particularly for designs incorporating multiplexing and synchronization.

It is very easy to synchronize delta-sigmaconverters together, so that they sample atthe same time but it's more difficult to synchronize a delta-sigma converter to anexternal event. Delta-sigma converters arehighly resistant to system clock jitter. Theaction of oversampling effectively averagesthe jitter, reducing its impact on noise.

Many delta-sigma converters include inputbuffers and programmable gain amplifiers(PGA). An input buffer increases the inputimpedance to allow direct connection to highsource impedance signals. A PGA increasesthe converter’s resolution when measuringsmall signals. Bridge sensors are an exampleof a signal source that can take advantage ofthe PGA within the converter.

Every ADC requires a reference, and for high-resolution converters, low-noise, low-drift references are critical. Most delta-sigma converters have differential reference inputs.

The following pages provide a broad rangeof delta-sigma ADCs available from TI for a wide range of applications.

Traditionally, industrial delta-sigma ADCs offering good drift performance used digital filters with largepassband droop. As a result, they have limited signal bandwidth and are mostly suited for DC measure-ments. High-resolution ADCs in audio applications offer larger usable bandwidths, but the offset and driftspecification are significantly weaker than their industrial counterparts. The ADS1271, ADS1274 andADS1278 combine these converter types, allowing high-precision industrial measurement with excellentDC and AC specifications ensured over an extended industrial temperature range.

Wide Bandwidth ∆Σ ADCs

TI’s wide bandwidth Delta-Sigma (∆Σ) ADCsare capable of very high resolution and arecapable of converting signals over a very widerange of frequencies from DC to severalmegahertz. Systems using these ADCs benefitfrom high speed, precision performance, andwide bandwidth (DC to 5MHz).

These ADCs employ a multi-stage propriatary-modulator architecture, which offer the advan-tage of inherent stability, and higher SQNRwith lower oversampling ratio (OSR).Furthermore, these high-speed, ∆Σ convertersare highly resistant to system clock jitter. Theaction of oversampling effectively averages thejitter, reducing the impact on noise.

The combination of speed and precisionenable wide bandwidth signal processingapplications for advanced scientific instrumen-tation for biomedical, bench test and measure,and communications applications.

SAR ADCs

Successive-approximation register (SAR) converters are frequently the architecture ofchoice for medium-to-high-resolution applications with medium sampling rates.SAR ADCs range in resolution from 8- to 18-bits with speeds typically less than10MSPS. They provide low power consumption and a small form factor.

A SAR converter operates on the same principleas a balance scale. On the scale, an unknownweight is placed on one side of the balancepoint, while known weights are placed on theother side and rejected or kept until the twosides are perfectly balanced. The unknownweight can then be measured by totaling upthe kept, known weights. In the SAR converter,the input signal is the unknown weight, whichis sampled and held. This voltage is then compared to successive known voltages, andthe results are output by the converter. Unlikethe weigh scale, conversion occurs very quickly through the use of charge redistributiontechniques.

Because the SAR ADC samples the input signaland holds the sampled value until conversion iscomplete, this architecture does not make anyassumptions about the nature of the input signal, and the signal therefore does not needto be continuous. This makes the SAR architecture ideal for applications where amultiplexer may be used prior to the converter, or for applications where the converter may only need to make a measurement once every few seconds, or forapplications where a “fast” measurement isrequired. The conversion time remains thesame in all cases, and has little sample-to-conversion latency compared to a pipeline ordelta-sigma converter. SAR converters areideal for real-time applications such asindustrial control, motor control, power management, portable/battery-poweredinstruments, PDAs, test equipment anddata/signal acquisition.


Modern SAR ADCs use a sample capacitorthat is charged to the voltage of the inputsignal. Due to the ADC's input capacitance,input impedance, and external circuitry, a settling time will be required for the samplecapacitor's voltage to match the measuredinput voltage.

Minimizing the external circuitry's sourceimpedance is one way to minimize this settling time, assuring that the input signal isaccurately acquired within the ADC’s acquisitiontime. A more troublesome design constraint,however, is the dynamic load that the SARADC's input presents to the driving circuitry.The op amp driver to the ADC input must beable to handle this dynamic load and settleto the desired accuracy within the requiredacquisition time.

The SAR ADC's reference input circuitry presentsa similar load to the reference voltage. Whilethe reference voltage is supposed to be a verystable DC voltage, the dynamic load that theADC's reference input presents makes achieving

this goal somewhat difficult. Thus, buffer circuitry is required for the reference voltage, and the op amp used for this hassimilar requirements as that used for drivingthe ADC input; in fact, the requirements onthe op amp may be even higher than for theinput signal as the reference input must be settled within one clock cycle. Some convertershave this reference buffer amplifier built in.

Buffering these inputs using op amps with alow, wideband output impedance is the bestway to preserve accuracy with these converters.

To help facilitate the selection process, an interactive online data converter parametric search engine is available at dataconverter.ti.com with links to all data converter specifications.

In a SAR ADC, the bits are decided by a single high-speed, high-accuracy comparator bit by bit, from the MSB down to the LSB. This is done by comparing the analog input with a DAC whose output is updated by previously decided bits and successively approximates the analog input.

Pipeline ADCs

Analog-to-digital converters featuring samplingrates of 10s of MSPS are likely based on thepipeline architecture. The pipelined ADC consists of N cascaded stages. The concurrentoperation of all pipeline stages makes thisarchitecture suitable for achieving very highconversion rates. The stages themselves are essentially identical, lined up in an assemblyline fashion and designed to convert only aportion of the analog sample. The digital output of each stage is combined to producethe parallel data output bits. A new digitizedsample becomes available with every clockcycle. The internal combination process itselfrequires a digital delay, which is commonlyreferred to as the pipeline delay, or datalatency. For most applications this is not a limitation since the delay, expressed in number of clock cycles, is a constant and canbe accounted for.

One of the key architectural features ofpipeline ADCs that allows high dynamic performances at high signal frequencies isthe differential signal input. The differentialinput configuration results in the optimumdynamic range since it leads to smaller signalamplitude and a reduction in even-order harmonics. Almost all high-speed pipelineADCs use a single-supply voltage, rangingfrom +5V down to +1.8V. Therefore, mostrequire the analog input to operate with acommon-mode voltage, which typically is atthe mid-supply level. This common-mode orinput bias requirement comes into considera-tion when defining the input interface circuitry that will drive the ADC. Switchedcapacitor inputs should also be considered.


Pipeline ADCs also employ the basic idea of moving charge samples, which represent the input voltage level at the particular sample incident, from one stage tothe next. The differential pipeline structure ishighly repetitive where each of the pipelinestages consists of a sample-and-hold (S/H),a low-resolution ADC and DAC, and a sum-ming circuit that includes an interstage amplifier to provide gain.

The analog signal is sampled with the firstS/H circuit, which may also facilitate a single-ended to differential conversion. This S/H isone of the most critical blocks as it typicallysets the performance limits of the converter.As the captured sample passes through thepipeline, the conversion is iterated by thestages that refine the conversion withincreasing resolution as they pass theremainder signal from stage to stage. Eachstage performs an analog-to-digital conver-sion, and a back-conversion to analog. Thedifference between the D/A output and theheld input is the residue that is amplifiedand sent to the next stage where thisprocess is repeated.

In order to properly design the interface circuitto the pipeline ADC, its switched-capacitorinput structure needs to be considered. Theinput impedance of the pipeline converterrepresents a capacitive load to the drivingsource. Furthermore, it is dynamic since it isa function of the sampling rate (1/fs). Theinternal switches generate small transientcurrent pulses that may affect the settlingbehavior of the source. To reduce the effectsof this switched-capacitor, input series resistors and a shunt capacitor are typically recommended. This will also ensure stability and fast settling of the drivingamplifier.

To select an appropriate interface circuit configuration, it is important to determinewhether the application is time domain innature (e.g. CCD-based imaging system) or afrequency domain application (e.g. communi-cation system). Time domain applicationsusually have an input frequency bandwidththat includes DC. Frequency domain applica-tions, on the other hand, are typically ac-coupled. The key converter specificationshere are SFDR, SNR, aperture jitter and analog input bandwidth; the last two specifications particularly apply to undersampling applications. The optimuminterface configuration will depend onwhether the application calls for widedynamic range (SFDR), or low noise (SNR), or both.

Critical to the performance of high-speedADCs is the clock signal, since a variety ofinternal timing signals are derived from thisclock. Pipeline ADCs may use both the risingand falling clock edge to trigger internalfunctions. For example, sampling occurs onthe rising edge prompting this edge to havevery low jitter. Clock jitter leads to aperturejitter, which can be the ultimate limitation inachieving good SNR performance. Particularlyin undersampling applications, special consideration should be given to clock jitter.

DACs by Architecture

Delta-Sigma (∆Σ) DACs

69

Delta-sigma (∆Σ) DACs are the converse of delta-sigma ADCs with a digital modulator and analog filter. ∆Σ DACsinclude a serial interface, control registers, modulator, switched capacitor

filter and a clock for the modulator and filter.∆Σ DACs have high resolution and lowpower making them ideal for closed-loop control in industrial control applications,high-resolution test and measurement

equipment, remote applications, battery-powered instruments and isolated systems.

Resistor "String" and R-2R DACs consist of three major elements: logic circuitry; sometype of resistor network means of switchingeither a reference voltage or current to theproper input terminals of the network as afunction of the digital value of each digitalinput bit, and a reference voltage.


R-2R DACs—are used to achieve the bestintegral linearity performance. In an R-2RDAC, a current is generated by a referencevoltage, which flows through the R-2R resistor network based on the digital input,which divides the current by two at each R-2R node. The advantage of a R-2R type

DAC is that it relies on the matching of the R and 2R resistor segments and not theabsolute value of the resistors thus allowingtrim techniques to be used to adjust the integral linearity and differential linearity.

Voltage Segment DACs (String DACs)—are simply a string of resistors, each of value R.The code loaded into the DAC register determines at which node on the string thevoltage is tapped off to be fed into the output amplifier by closing one of theswitches connecting the string to the amplifier. The DAC is monotonic, because itis a string of resistors. In higher resolution12- and 16-bit DACs, two resistor strings areused to minimize the number of switches in

the design. In a two-resistor string configuration, the most significant bits drivea decoder tree, which selects the voltagesfrom two adjacent taps of the first resistorstring and applies them to the inputs of twobuffers. These buffers then force these voltages across the endpoints of the secondresistor string. The least significant data bitsdrive a second decoder tree, which selectsthe voltage at one of the switch outputs anddirects it to the output buffer.

DAC5682Z functional block diagram.

Key Features• 16-bit LVDS input data bus• 8 sample input FIFO• Interleaved IQ data for dual DAC mode• Superior ACLR/ACPR performance• 2x-32x clock multiplying PLL• 2x or 4x selectable interpolation filters• Configurable low pass/high pass option• Fs/4 mixer• Scalable differential outputs: 2 to 20mA• Package 64-pin QFN (9x9)

Applications• Cellular base stations• Broadband wireless access• WiMAX / 802.16• Fixed wireless backhaul• Cable modem termination systems• Test equipment

The DAC5682Z is designed to enable the conversion of wide bandwidth signals from digital toanalog. The LVDS interface enables the input of high data rates while controlling EMI emissionsand reducing footprint size of the device. Several configurable features the device also savecost, such as the on-board multiplying clock which eliminates the use of expensive off-chipclocking. In addition, the low-pass/high-pass interpolation filters and digital mixer optionsenables system design flexibility.

Modern high-speed DACs, fabricated on submicron CMOS or BiCMOS processes,have reached new performance levels withupdate rates of 500MSPS and resolutions of14- or even 16-bits. In order to realize suchhigh update rates and resolutions, the DACsemploy a current-steering architecture with segmented current sources. The core elementwithin the monolithic DAC is the currentsource array designed to deliver the full-scaleoutput current, typically 20mA. An internaldecoder addresses the differential currentswitches each time the DAC is updated.Steering the currents from all currentsources to either of the differential

outputs forms a corresponding signal outputcurrent. Differential signaling is used toimprove the dynamic performance whilereducing the output voltage swing that isdeveloped across the load resistors. Ideally,this signal voltage amplitude should be assmall as possible to maintain optimum linearityof the DAC. The upper limit of this signalvoltage, and consequently the load resistance,is defined by the output voltage compliancespecification.

The segmented current-steering architecture provides a significant reduction in circuit complexity and consequently in reducedglitch energy. This translates into an overall

improvement of the DAC’s linearity and ac performance. As new system architecturesrequire the synthesis of output frequencies in the 100s of MHz range, an approach oftenreferred to as “direct IF” achieves highupdate rates, while maintaining excellentdynamic performance.

The ADS120x series are 2nd-order, precision, delta-sigma (∆Σ) modulators operating from a single +5V supply at a 10MHz clock rate,specifically used in motor control applicationsfor measuring and digitizing motor current. Thetargeted application is servo motor control.

Both the ADS1202 and ADS1203 modulatorshave an input range set for ±250mV to directlydigitize current passing through a shunt resis-tor. The ADS1204 and ADS1205 are optimized

for magnetic-based current sensors and featuretwo and four input channels. In contrast, theADS1208 is optimized for Hall Effect sensors.

Precision Voltage and Current

References

TI’s family of voltage and current referencesincorporates state-of-the-art technology tooffer stable, high-precision, high-performancereferences in tiny packages.

Series Voltage References

Series voltage references are known forexcellent accuracy and stability over temperature. Typically three terminaldevices, series voltage references are oftenused to provide stable reference voltages for ADCs and microcontrollers.

The REF29xx, REF30xx, REF31xx and REF32xxare TI’s newest available families of precision,low-power, low-dropout, series voltage references in tiny SOT23-3 packages. Driftspecifications range from 100ppm/°C to lessthan 10ppm/°C. Small size and low powerconsumption (100µA typ) make them ideal forportable and battery-powered applications.

Current References

Many applications require the use of a precision current source or current sink. TheREF200 combines three circuit building-blockson a single monolithic chip—two 100µA current sources and a current mirror capableof being used as a current source or sink.

Integrated Op Amp and Voltage

References

For applications requiring an op amp plusvoltage reference or comparator plus voltagereference, TI has an offering of integratedfunction voltage references. The TLV3011 andTLV3012 are low-power, (5µA) 6µs propagationdelay comparators with an integrated shuntvoltage reference.

See pages 24 -25 for comparator

and integrated voltage reference

specifications

These voltage references are stable with anycapacitive load and can sink/source a minimumof up to 10mA of output current and arespecified for the temperature range of –40°Cto +125°C.

Shunt Voltage References

Shunt voltage references are precision diodesdesigned to offer good accuracy at extremelylow power. These devices require a currentsource, typically a supply voltage and pull-upresistor to keep forward biased.

The REF1112 is a 1µA, two-terminal reference diode designed for high accuracy with outstanding temperature characteristics at low operating currents.Precision thin-film resistors result in 0.2% initial voltage accuracy and 50ppm/°C maximum temperature drift. The REF1112 isspecified from –40°C to +85°C, with operationfrom 1µA to 5mA, and is offered in a SOT23-3 package.

Digital Temperature Sensors

TI’s high-accuracy, low-power temperature sensors are specified for operation from –40°Cto +125°C and are designed for cost-effectivethermal measurement in a variety of communication, computer, consumer, industrial and instrumentation applications.

These silicon-based temperature sensors aredesigned on a unique topology that offersexcellent accuracy and linearity over temperature. Low power and standard communication protocol pair nicely with low-power microcontrollers and battery-powered designs.

The digital temperature output of the TMP family is created using a high-performance, 12-bit, delta-sigma ADC that outputs temperatures as a digital word. Programmingand communication with the TMP1xx family ofdevices is done via an I2C/2-wire or SPI interface for easy integration into existing digital systems.

Temperature Sensor Core

A typical block diagram of the TMP family ofdigital temperature sensors is shown below.Temperature is sensed through the die flag ofthe lead frame where the temperature sensingelement is the chip itself, ensuring the mostaccurate temperature information of the monitored area and allowing designers torespond quickly to “over” and “under” thermal conditions.

Features of TMP Digital

Temperature Sensors

Several TMP digital sensors offer programmable features, including over- and under-temperature thresholds, alarm functions and temperature resolution. Withextremely low power consumption in active(50µA) and standby (0.1µA) modes, theTMP12x family offers as low as 1.5°C minimum error in a SOT23 package and isan excellent candidate for low-power thermal monitoring applications.

Signal Chain Prototyping System

104

Use modular Evaluation Modules (EVMs)to prototype a complete data acquisitionsystem in minutes!

Imagine being able to prototype your entiresignal chain—input signal conditioning, A/Dconversion, processor, D/A conversion andoutput signal conditioning–with simple building blocks. Imagine not havingto lay out a printed circuit boardjust to evaluate a system signalprocessing idea.

With TI's modular EVM building blocks,you can put together a complete data acquisition system featuring signal condition-ing, an A/D converter and a processor—all injust a few minutes. For a more complete system you can add on from there—a D/Aconverter, or more output signal conditioning.With modular EVM boards that go togethereasily, thanks to standardized connectors, youcan quickly build a complete hardware prototype and get to writing your applicationcode faster.

You can also build your own modules to fitthis system, to accommodate circuits that maynot be available directly from TI. Refer to thelinks at the end of this guide to find out howthe system is defined. Get More Information:

Start with the Processor

The processor is the heart of your system. Doyou need the power of a DSP, or the featuresof a microcontroller? You're free to chooseand explore these options with the modularEVM system. The signal chain building blockshave the ability to easily snap into place onan interface card to connect them to most ofTI's DSPs.

Don't need a DSP? TI's ultra-low-powerMSP430 microcontroller products andMicroSystem Controllers feature built-in analog functionality. In many systems, external data conversion components may

be needed to complement the built-infunctions. For those cases, our broad rangeof data conversion products can be used withthese microcontrollers.

Using FPGAs instead of a processor? Some distributors of FPGAs have developedinterface boards that allow the signal chainbuilding blocks to connect to their FPGAdevelopment systems.

If you just want to evaluate the device on the EVM using standard lab equipment, orwant to try wiring the board into your existing system, the modular EVMs will allow for that as well, no processor needed.You have access to all the essential interfacepins on the device through the standardizedconnectors. So no matter how you processthe data, we've got a way to help you develop your system.

Ready to Get Started?

If you've decided to use a DSP in your system, an interface card may be required toconnect your DSP Starter Kit (DSK) to themodular EVMs. Refer to the table at the endof this article to see which interface isrequired for your DSK. A listing of EVMs compatible with our DSKs can be found onthe TI eStore. www.ti-estore.com

If the TMS470 microcontroller is what youare using, the TMS470 System DevelopmentBoard was designed to fit on the HPA-MCUInterface Board.

Developing with Modular EVMs

Developing software with the modularEVMs is easy. If you're using a DSP,

our free Data Converter SupportPlug-In for Code Composer Studio™

Studio integrated development environ-ment (IDE) can help you set up the DSP to

interface with the data converters.

If you are developing TMS470 code with IAREmbedded Workbench, you can use the JlinkUSB-JTAG Debugger to download programsto the TMS470R1B1M.

Code Examples

Code for use with the modular EVMs on thedifferent platforms can be found in the toolfolder for the EVM. Look for the RelatedSoftware section in Related Documents inthe tool folder. Very often, this code is a simple project that runs on the processorused; in some cases, complete software toevaluate data converters that runs on your PC is included as well.

The data converter support plug-in residing inTI’s Code Composer Studio IDE makes it easierthan ever to design with TI data converterproducts along with TI’s TMS320™ digital signal processors (DSPs).

Using the free tool in the Code ComposerStudio IDE reduces the time required to configure data converters by up to 90 percent.The plug-in software module generates initialization data and interface software forthe user’s data converter/DSP combinationusing a graphical user interface, along withthe necessary data structures. For many dataconverter EVMs and DSP Starter Kit (DSK)combinations, complete software examplescontaining source code and pre-coded executables to run the data converter areavailable. The software examples show howto design with the data converter by usingthe interface software generated by the dataconverter plug-in module (DCP).

Software Saves Configuration Time

Today, state-of-the-art data converters arehighly integrated, requiring configuration forinput channel selection, filters, interfaces,

adjustable gain control, offset cancellation,integrated first-in-first-out (FIFO) memory andother features. Creating data converter interface software can complicate the development effort. TI data converters andthe interface software simplify the softwaredevelopment task, reducing time-to-marketfor applications using TI DSPs.

The DCP is a component of TI’s industry-lead-ing Code Composer Studio IDE and offerseasy-to-use windows for “point-and-click”configuration, preventing illegal combinationsof settings. The DCP automatically createsthe interface software as the C source codenecessary to use the data converter, theninserts the code into the existing user project. The created files contain the functions necessary to initialize the data converter, read/write sample values and toperform special functions (like power-down).

Innovations in Design Support

TI merges DSP hardware, DSP software anddata converters to simplify the designprocess with a comprehensive DSP solutionthat includes peripherals.

Support is available for data converters usedwith TI’s C28x™, C54x™ , C55x™, C62x™,C64x™ and C67x™ DSP generations.

The easy-to-use support software benefitsdevelopers of wireless data networking,portable audio, voice-over-packet, digitalimaging, speech, motor control and a widerange of other advanced DSP-based applications.

The software has been fully tested in conjunction with the DSK and the data converter EVMs. Help files are included alongwith the data converter information in theplug-in module. These features minimize riskand ease the learning curve so the DSPdesigners can start system developmentquickly, concentrating their efforts in areas ofproduct innovation to improve the value oftheir intellectual property and get the greatestreturn of investment.

Using TI’s Data Converter InterfaceSoftware

TI is committed to complementing its DSPswith a full range of data converters. Interfacesoftware for new DSP-optimized TI data converter products is planned, includingDACs and ADCs, as well as codecs andselected special function devices.

The DCP module and the already availabledata converter software for more than 125data converters is included with the CodeComposer Studio IDE. To order CodeComposer Studio IDE, visit our web page atdspvillage.ti.com

As new interface software is developed, itwill be made available as part of the DCPmodule. The new versions can be down-loaded and installed in the Code ComposerStudio IDE, versions 2.0 and higher.

Updates to the DCP module can be downloaded free of charge fromwww.ti.com/dcplug-in



Evaluation Boards and ADCPro™ Software Make ADC Testing Easier

106

When you consider an analog-to-digitalconverter (ADC) for a new design, you canget a rapid assessment of the device with anevaluation module. If you intend to viewcollected time-domain, histogram, or FFTdata, a new tool from TI, ADCPro, will assistin performing these tests.

IEEE Std 1241-2000 defines how thesestandard tests are to be performed. There areDC and AC parameters for ADCs – and theIEEE standard describes several differentpossible ways of testing these parameters.The simplest method is to use a sine wavesignal source and look at the resulting datarecord in several ways. These include timedomain plots, histograms, and FFT tests.Using these three methods together will giveus a good indication of what the ADCtransfer characteristics are.

At TI, our ADC EVMs are produced in amodular format. This small card provides theminimal circuitry needed to make the ADCoperate—in some cases a reference voltage,or a clock source (oscillator) is needed. Byitself, it provides a means for customers toconnect the ADC into their own system ortest platform. Using our modular EVMinterface boards, these EVMs can beconnected to TI processors for use in codedevelopment and hardware prototyping.

To assist evaluation of the converters, weprovide complete evaluation kits (identified byending in "EVM-PDK" example ADS1258EVM-PDK). These "PDKs" consist of the modularEVM, plus a suitable motherboard to plugthem into—this provides the means to collectdata from the device and communicate thatdata to a computer, usually through a USBconnection. In addition, analog-to-digitalconverter PDKs will include some software tohelp control the device under evaluation andanalyze the data collected. This data analysissoftware is called ADCPro. Like the EVMs,ADCPro is designed in a modular fashion,using the concept of plug-ins to supportdifferent devices and different tests andanalyses.

When you run ADCPro, you really use threeprograms: a shell program that loads plug-ins,a plug-in program that can communicate withthe hardware of an EVM, and a test plug-inthat analyzes data coming from the EVMplug-in. This modular design allows ADCProto be used with a number of different datacapture cards or motherboards that may shipin the EVM-PDK. Data files saved fromADCPro can be reloaded for further analysisusing an EVM plug-in that simply reads files.

When considering an analog-to-digitalconverter for a new design, using an

evaluation kit and ADCPro software can helpyou quickly determine the performance levelof the converter to see if it meets your needs.Following the IEEE1241-2000 standard, youcan use a simple sine wave input and viewcollected time-domain, histogram, or FFTdata, and get a sense of how the ADC willperform in your application.

Data Converter Plug-In (DCP) for Code Composer Studio™ IDE

107

TI’s Data Converter Plug-In (DCP) is a freedevelopment tool that allows the creation ofinitialization data and configuration softwarefor TI data converters from within theIntegrated Development Environment (IDE) ofCode Composer Studio™. It provides easy-to-use windows for “point-and-click” data converter configuration from within the IDE, preventing illegal combinations of settings.The DCP dialog allows the user to select allthe different settings for the data converterfrom a single screen and to automaticallygenerate the interface software with a

single mouse click. The generated well-documented C source files contain all functionsnecessary to talk to the external data converter and to set up all of the registersinternal to this device. The minimum functionset includes read/write functions (singlewords and blocks of data), initialization functions and data structures and somedevice-specific functions like power down.

The generated code is to a great extent hardware independent, so it can be usedtogether with the analog evaluation

modules (EVMs) from our modular EVM system, our DSP Starter Kits (DSKs) or withyour own custom board.
