Analog-Input Class-D Speaker Amplifiers

Output Power per Channel

• Maximum power is decided primarily by power supply (output voltage and current) and speaker impedance.

• Efficiency of Class-D amplifiers is typically between 80% and 90%, which reduces demands on the power supply design.

• The maximum input signal level dictates the required power amplifier gain to achieve the desired output power.

• For best noise performance, the gain should be as low as possible.

Output Filter Design

• Most of TI’s Class-D amplifiers operate without a filter when speaker wires are less than 10cm.

• When speaker wires are long, place a second-order low-pass (LC)filter as close as possible to the amplifier’s output pins.

• The filter must be designed specifically for the speaker impedancebecause the load resistance affects the filter’s quality factor, or “Q.”

• A ferrite bead may also eliminate very high-frequency interference.

PCB Layout

• Place decoupling capacitors and output filters as close as possibleto the amplifier IC.

• When using a ferrite bead filter place the LC filter closest to the IC.

• Always connect the PowerPAD™ connection to the power ground.

• When the PowerPAD package serves as a central “star” ground for amplifier systems, use only a single point of connection for the analog ground to the power ground.

• After determining the number of speakers in a system, specify theoutput power for each channel.

• Maximum power is decided primarily by:•• Power supply (output voltage and current)•• The amplifier’s maximum output voltage•• Speaker impedance

• Maximum efficiency is ~40% with Class-AB amplifiers.

• The power supply must provide continuous current to support thedesired maximum power.



Heat

• Class-AB amplifiers run hotter than equivalent Class-D amplifiers.

• Driving 2W per channel in stereo systems generates 6W of heatwith an efficiency of ~40%.

• TI’s Class-AB speaker amplifiers feature the PowerPAD™ package,using a PCB as a heatsink.

• See the application brief “PowerPAD™ Made Easy” for package layout and other design considerations at:http://focus.ti.com/lit/an/slma004b/slma004b.pdf

Features

• Class-AB amplifiers offer several different ways to control the gain or volume:•• External resistors (similar to traditional op-amp circuits)•• Integrated gain-setting resistors•• DC volume control•• I2C volume control

• Most of TI’s portfolio provides the three latter control options.

• When a headphone drive is part of the design, most Class-AB amplifiers with TTL-input pins can change outputs from bridge-tiedload (BTL) to single-ended (SE) configurations, eliminating the needfor an additional amplifier.

Headphone Amplifiers

Issues to Consider When Using Single-Ended Power Supplies

• Many amplifiers work at single +3.3-V or +5-V supplies.

• These power supplies require a DC-biased amplifier output toensure undistorted output.

• Placing DC-blocking capacitors between the speaker and the amplifier causes a high-pass filter and equates to poor bass response.

• TI counters this high-pass filter issue with capless and DirectPath™technologies. •• Capless creates a virtual ground (VDD/2) for the headphone

connector. Both amplifier outputs then have a VDD/2 bias, ensuring that no DC passes through a speaker.

•• DirectPath-enabled devices include an internal charge pumpwhich creates a negative power rail inside the device. With thisdesign, an amplifier can be powered by a bipolar supply and have an output biased to ground.

Headphone Impedance and Power

• Headphone impedances can vary greatly, from 16Ω to 600Ω.

• When choosing an amplifier, always ensure that it can handle thepower at the specified voltage range and headphone impedance.

Low-Power Audio Amplifier Sub Systems

Radio Emission Interference in Notebook PCs

• RF emissions from mobile data add-in cards, 802.11 and Bluetooth®

radios can create noise problems for amplifiers.

• It can be particularly problematic if the amplifiers, codecs or speakers are separated from each other by industrial or boarddesign requirements.

• For additional design flexibility, use devices with differential inputs,which provide significantly better noise immunity.

Headphone Outputs Serving as Line Outs

• Traditional Class-AB design allowed headphone outputs to be usedas line outs.

• The size and expense of DC-blocking capacitors has led to caplessmethods to implement output.

• VBias on ground sleeve removes the caps, but can inject a hum or damage the amplifier if ground loopback occurs with an external device.

• DirectPath™ solutions eliminate ground loopback and improve bass response.

Microphone Preamplifiers

Control Methods: Analog vs. Digital

• Analog control microphone preamplifiers typically use a variableresistor on a product’s front panel that can be changed during performance.

• Digitally controlled microphones are remotely controllable and haveeasily recallable settings, offering significant advantages whencompared to their analog control counterparts.

• In the live sound and recording industry, digitally controlled microphones allow signals to be preamplified and converted closer to the source rather than sending tiny µV signals acrossmeters of cable.

Equivalent Input Noise (EIN) Considerations

• EIN is a key specification in defining a microphone preamplifier.

• At a given gain, microphone preamplifiers exhibit a certain amountof input noise that is amplified together with the audio source.

• Ideally, microphone preamplifiers will have low EIN values to ensurethat only the audio source is amplified instead of the noise.

Outputs: Differential vs. Single-Ended

• Inside a product, a single-ended output is sufficient to process signals needing further processing.

• Many high-performance ADCs require differential inputs. If theamplified differential microphone signal is taken directly to an ADC,a differential output will give an additional 6dB of dynamic range.

• Differential outputs from a microphone preamplifier will help ensure that the differential input on the receiver will reject any common-mode interference induced on the cable by cancelling out the common noise on both connections.

Driving 2VRMS for Audio/Visual Applications

• Almost all audio coming into a television has a ground-centered 2VRMS output.

• Most audio DACs have a sub-4VPP with a DC bias ~2.5V.

• The traditional solution for generating a ground-centered 2VRMSoutput is to run an output op amp stage from a higher voltage bipolar power supply (±12V).

• This solution adds complexity, especially if the rest of the devicesare using only 3.3V or 5V.

• TI’s DRV60x family integrates the amplifier and charge pump to create positive and negative rails for clean, ground-centered 2VRMS output.

Balanced-Line I/O for Professional Audio Applications

• Balanced-line I/O is used in professional audio environments: live,recording and broadcast to keep signals clean and interference free.

• By having equal impedance to ground on both conductors, balanced-line I/O offers two advantages: •• The noise induced is near equal and should be cancelled by a

balanced-line receiver as common-mode noise•• Having inverted signals on both conductors also adds another

6dB to the dynamic range for the same supply voltage

Overall Op Amps

• When selecting an op amp, investigate its input stage.

• FET-based op amps usually have a very high input impedance.

• FET-input devices are ideal when the output impedance of thesource isn't easily known, such as with a musical instrument.

• BJT (bipolar)-based op amps exhibit lower input impedance and offer lower input noise.

• Bipolar op amps are ideal input devices for low-impedance outputsources requiring low noise amplification.

DAC Output Attenuation

(DAC output level ~2VRMS)

Volume Controls

Supply Voltage: Signal Swing

• DAC outputs typically have a swing of around 3VPP.

• Broadcast signal swings can easily be 25VPP or higher.

• Knowledge of the signal amplitude that will be attenuated is criticalwhen choosing digitally controlled analog volume controls.

• For controlling DAC output, ±5-V devices are more than adequate to provide 10-VPP headroom for a signal that, at maximum, will bebelow 5VPP.

Maintenance of Dynamic Range

• Multiplying the DAC’s digital value by < 1 is an acceptable way tocontrol volume for many applications, using fewer bits to representthe signal while the noise level remains the same.

• Combining fewer bits to represent a signal with a fixed-noise levelwill increasingly reduce the dynamic range as the volume changes.

• By changing the volume in the analog domain while under digitalcontrol, the DAC’s inherent noise will be attenuated along with the audio.

Reducing Noise on Microphone Inputs

• Microphone signals are susceptible to noise injection due to the low peak-to-peak range of 10mV.

• Placing the codec or ADC close to the microphone often conflictswith user preference, industrial design or mechanical designrequirements.

• Look for devices which can work with digital microphones or have differential inputs, both of which provide significantly better noise immunity.

Processing Allocation and Software Reusability

• Host processors in handheld consumer electronics are being given more tasks, pushing processor MIPS allocations and design schedules.

• One solution is to offload a number of audio functions to a DAC or codec.•• Audio functions include 3-D effects, equalization, notch filters

or noise cancellation•• Look for devices with broad, easy software reusability and

the ability to allocate the processing to either input or output functions

Simultaneously Handling Multiple Audio Sources

• Designers of handheld consumer electronics don’t have the option of focusing on a single sample rate or audio signal source. Withmultiple functions come different radios and sampling rates. Look for codecs with:•• Multiple independent analog and digital interfaces•• The ability to independently sample and process these

two signals

Home and Professional Audio Converters

Dynamic Range

• Home and professional audio converter performance is measured in dynamic range, not bit depth.

• A 24-bit converter describes its output format, not its quality.Therefore, many of the least significant bits in a 24-bit audio wordmay be noise.

• At its peak, a standard CD has 98.08-dB (16 bit) dynamic range.

• In professional environments, a converter may have a dynamicrange of up to 132dB.

Analog Integration and Multichannel Support

• TI's highly integrated range of consumer converters support complexsignal-chain designs.

• Integrating functionality such as multiplexers, programmable gainand S/PDIF transmitters into a single package reduces cost, designcomplexity and time to market.

Control Methods

• Converters can be controlled in many different ways; many simplyby tying pins high and low.

• A small micro, SPI shift register or I2C expander can allow controlfrom a remote source.

• For products with increased integration, control is typically througheither SPI or I2C.

• When choosing converters or codecs, confirm both the controlmethod and the existence of additional I/O (GPIO, SPI or I2C) for the main processor to support the device.

Audio Converters with Integrated Touch-Screen Controller

Using Touch-Screen Controllers (TSCs) to OffloadHost Processing

• TSCs detect contact and then require the host to handle as many as 40 to 50 register read/write cycles.

• These requirements create additional interrupts and processingcycles, which reduces processing efficiency.

• To reduce this load on the host, look for “smart” TSCs with the ability to generate coordinates with minimal interaction from the host.

Other Methods for Using TSCs to Offload Host Processing

• Host processors in handheld consumer electronics are being given more tasks, pushing processor MIPS allocations and design schedules.

• One solution is to offload a number of audio functions to the DAC or codec functions of a TSC. •• Audio functions include 3-D effects, equalization, notch filters

or noise cancellation•• Look for devices with integrated audio, software reusability

and the ability to allocate the processing to either input or output functions

Supporting Varying Mechanical System Designs

• The preferred solution with a single integrated TSC + audio device ora discrete TSC and audio codec may depend on whether a handheld device is built on:•• A single-board platform, such as a candy bar•• A PDA form factor•• An in-dual board platform like a flip phone

• TI offers a wide selection of stand-alone TSCs and audio codecs aswell as integrated TSC + audio devices for all types of system designs.

16 Interface and Sample Rate Converters

Design Considerations for S/PDIF Interface and Sample Rate Converters

Sample Rate Converters (SRCs)

• SRCs create sample rate and phase-independent interfaces between fixed-rate digital processors and the outside world.

• SRCs can serve as “jitter cleaners,” lowering the amount of jitter on incoming data streams.

• SRCs allow similar phase-independent sample rates to be broughtinto systems without the need for time alignment/word clock distribution.

Jitter Sensitivity

• Jitter can be a major problem in a digital audio system.

• Jitter is introduced when digital audio clocks are generated orregenerated from a different clock source and by using interconnectsthat have significant parasitic impedance (capacitance, inductanceetc.).

• Jitter in digital audio systems moves the sampling instant back and forth in time, adding noticeable distortion in high frequencies.

• For the smallest adverse impact on the audio content, choose S/PDIF receivers with low jitter.

System Partitioning

• System partitioning options include discrete transmitters, receiversand stand-alone SRCs, as well as combinations of transceivers and SRCs.

• Flexible functionality allows end products to be either:•• A clock master (and SRC from the outside to its internal

process clock)•• A slave to an external clock (and SRC the output to the new

clock rate)

Digital Audio Processors

Input Considerations

Audio SoC inputs can be digital or analog.

• Digital inputs in the I2S form are suitable if the audio source is digital in nature, such as an MP3 decoder or DSP.

• Analog inputs can be either single ended or differential.

• Single-ended circuits are simpler and require fewer components.

• Differential circuits offer better noise performance.

• Differential inputs are robust against TDMA noise generated by mobile phones.

Audio Processing Considerations

The digital core of an audio SoC can be based on two types of architectures, ROM or RAM.

• ROM-based cores:•• Are not fully programmable•• Feature a fixed-process flow that can be configured

•Example: Each audio channel might have a bank of seven fixed-frequency bi-quad filters in which only the gains can be altered by a user

• RAM-based cores:•• Are fully programmable

•Example: A user can implement any desired number of bi-quad filters on a channel and specify gain, bandwidth, and center frequency

Output Considerations

Audio SoC outputs can be digital, analog or PWM.

• Digital outputs:•• Are in an I2S or S/PDIF form

•I2S is useful if the output signal is being sent to another IC•S/PDIF is generally used for an output that is expected to be

routed to an external audio system

• Analog outputs:•• Can be either single ended or differential•• Reference input consideration section for benefits of each type

of output

• PWM outputs:•• Can be routed directly to an H-bridge PWM power stage, such

as TI’s TAS53xx family•• Are beneficial because the audio stream is maintained as digital

for as long as possible

V+ and the Max Analog Signal Amplitude

• V+ determines the analog signal amplitude that can be passedwithout clipping for noncharge-pump switches.

• The gate(s) of the pass transistors must be biased relative to theminimum and maximum values of the expected input voltage range.

• Some switches allow for biasing from two supplies, making it easyto pass both positive and negative signals.

• Switches with integrated charge pumps can elevate the gate voltage above V+ (at the expense of larger I+) and thus pass signals of a magnitude greater than V+.

VIH/VIL Compatibility

• The signal switch is controlled by the output of a digital source inmost applications.

• The control signal levels, VIH and VIL, must be compatible with thedigital source to ensure proper operation of the switch.

On-State Resistance (ron) Tradeoffs

• ron contributes to signal loss and degradation.

• Non-charge-pump switches achieve low ron with large pass transistors.•• Leads to larger die sizes and increased channel capacitance (CI/O)•• Limits the frequency response of the switch

• Switches using charge-pump technology can achieve low ron andCI/O but require significantly higher I+.

On-State Resistance Flatness [ron(flat)]

• On-state resistance flatness specifies the minimum and maximumvalue of ron over the specified range of conditions.

• Conditions may include changes in temperature or supply voltage.
