DESCRIPTION
The 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.
