SINGLE, DUAL, and QUAD VERSIONS

DESCRIPTIONThe OPA234 series low-cost op amps are ideal forsingle-supply, low-voltage, low-power applications. Theseries provides lower quiescent current than older“1013”-type products and comes in current industry-standard packages and pinouts. The combination oflow offset voltage, high common-mode rejection, highpower-supply rejection, and a wide supply range pro-vides excellent accuracy and versatility. Single, dual,and quad versions have identical specifications formaximum design flexibility. These general-purpose opamps are ideal for portable and battery-powered appli-cations.The OPA234 series op amps operate from either singleor dual supplies. In single-supply operation, the inputcommon-mode range extends below ground and theoutput can swing to within 50mV of ground. Excellentphase margin makes the OPA234 series ideal for de-manding applications, including high load capacitance.Dual and quad designs feature completely indepen-dent circuitry for lowest crosstalk and freedom frominteraction.

Single version packages are in an SO-8 surface-mountand a space-saving MSOP-8 surface-mount. Dual pack-ages are in an SO-8 surface-mount. Quad packagesare in an SO-14 surface-mount. All are specified for–40°C to +85°C operation.

ELECTROSTATICDISCHARGE SENSITIVITY

This integrated circuit can be damaged by ESD. TexasInstruments recommends that all integrated circuits be handledwith appropriate precautions. Failure to observe proper han-dling and installation procedures can cause damage.

ESD damage can range from subtle performance degrada-tion to complete device failure. Precision integrated circuitsmay be more susceptible to damage because very smallparametric changes could cause the device not to meet itspublished specifications.

APPLICATIONS INFORMATIONThe OPA234 series op amps are unity-gain stable andsuitable for a wide range of general-purpose applications.Power-supply pins should be bypassed with 10nF ceramiccapacitors.

OPERATING VOLTAGE

The OPA234 series op amps operate from single (+2.7V to+36V) or dual (±1.35V to ±18V) supplies with excellentperformance. Specifications are production tested with +2.7V,+5V, and ±15V supplies. Most behavior remains unchangedthroughout the full operating voltage range. Parameterswhich vary significantly with operating voltage are shown inthe Typical Characterisitc curves.

OFFSET VOLTAGE TRIM

Offset voltage of the OPA234 series amplifiers is lasertrimmed and usually requires no user adjustment. TheOPA234 (single op amp version) provides offset voltagetrim connections on pins 1 and 5. Offset voltage can beadjusted by connecting a potentiometer, as shown in Fig-ure 1. This adjustment should be used only to null the offsetof the op amp, not to adjust system offset or offset pro-duced by the signal source. Nulling offset could degradethe offset drift behavior of the op amp. While it is notpossible to predict the exact change in drift, the effect isusually small.
