Low Power, Precision
SINGLE-SUPPLY OPERATIONAL AMPLIFIERS
FEATURES
● WIDE SUPPLY RANGE:
Single Supply: VS = +2.7V to +36V Dual Supply: VS = ±1.35V to ±18V
●GUARANTEED PERFORMANCE: +2.7V, +5V, and ±15V
●LOW QUIESCENT CURRENT: 250μA/amp
●LOW INPUT BIAS CURRENT: 25nA max
●LOW OFFSET VOLTAGE: 100μV max
●HIGH CMRR, PSRR, and AOL
●SINGLE, DUAL, and QUAD VERSIONS
DESCRIPTION
The OPA234 series low cost op amps are ideal for single supply, low voltage, low power applications. The series provides lower quiescent current than older “1013”-type products and comes in current industrystandard packages and pinouts. The combination of low offset voltage, high common-mode rejection, high power supply rejection, and a wide supply range provides excellent accuracy and versatility. Single, dual, and quad versions have identical specifications for maximum design flexibility. These general purpose op amps are ideal for portable and battery powered applications.
OPA234 series op amps operate from either single or dual supplies. In single supply operation, the input com- mon-mode range extends below ground and the output can swing to within 50mV of ground. Excellent phase margin makes the OPA234 series ideal for demanding applications, including high load capacitance. Dual and quad designs feature completely independent circuitry for lowest crosstalk and freedom from interaction.
Single version packages are DIP-8, SO-8 surface-mount, and a space-saving MSOP-8 surface-mount. Dual packages are DIP-8 and SO-8 surface-mount. Quad packages are DIP-14 and SO-14 surface-mount. All are specified for –40C° to +85°C operation.
