Low Power, PrecisionFET-INPUT OPERATIONAL AMPLIFIERS
DESCRIPTIONThe OPA130 series of FET-input op amps combine precisiondc performance with low quiescent current. Single, dual, andquad versions have identical specifications for maximumdesign flexibility. They are ideal for general-purpose, por-table, and battery operated applications, especially with highsource impedance.
OPA130 op amps are easy to use and free from phaseinversion and overload problems often found incommon FET-input op amps. Input cascode circuitry pro-vides excellent common-mode rejection and maintains lowinput bias current over its wide input voltage range. OPA130series op amps are stable in unity gain and provide excellentdynamic behavior over a wide range of load conditions,including high load capacitance. Dual and quad designsfeature completely independent circuitry for lowest crosstalkand freedom from interaction, even when overdriven oroverloaded.
Single and dual versions are available in DIP-8 and SO-8surface-mount packages. Quad is available in DIP-14 andSO-14 surface-mount packages. All are specified for–40°C to +85°C operation.
FEATURES LOW QUIESCENT CURRENT: 530µA/amp
LOW OFFSET VOLTAGE: 1mV max
HIGH OPEN-LOOP GAIN: 120dB min
HIGH CMRR: 90dB min
FET INPUT: IB = 20pA max
EXCELLENT BANDWIDTH: 1MHz

APPLICATIONS INFORMATIONOPA130 series op amps are unity-gain stable and suitablefor a wide range of general-purpose applications. Powersupply pins should be bypassed with 10nF ceramic capaci-tors or larger.
OPA130 op amps are free from unexpected output phase-reversal common with FET op amps. Many FET-input opamps exhibit phase-reversal of the output when the inputcommon-mode voltage range is exceeded. This can occur involtage-follower circuits, causing serious problems incontrol loop applications. OPA130 series op amps are freefrom this undesirable behavior. All circuitry is completelyindependent in dual and quad versions, assuring normalbehavior when one amplifier in a package is overdriven orshort-circuited.
OPERATING VOLTAGE
OPA130 series op amps operate with power supplies from±2.25V to ±18V with excellent performance. Although speci-fications are production tested with ±15V supplies, mostbehavior remains unchanged throughout the full operatingvoltage range. Parameters which vary significantly withoperating voltage are shown in the typical performancecurves.
OFFSET VOLTAGE TRIM
Offset voltage of OPA130 series amplifiers is laser trimmedand usually requires no user adjustment. The OPA130(single op amp version) provides offset voltage trim con-nections on pins 1 and 5. Offset voltage can be adjusted byconnecting a potentiometer as shown in Figure 1. Thisadjustment should be used only to null the offset of the opamp, not to adjust system offset or offset produced by thesignal source. Nulling offset that is not produced by theamplifier will change the offset voltage drift behavior of theop amp.

INPUT BIAS CURRENT
The input bias current is approximately 5pA at room tem-perature and increases with temperature as shown in theTypical Characteristic curve Input Bias Current vs Tempera-ture.
Input stage cascode circuitry assures that the input biascurrent remains virtually unchanged throughout the full inputcommon-mode range of the OPA130. See the TypicalCharacteristic curve Input Bias Current vs Common-ModeVoltage.
