OPA234 OPA234 OPA2234 OPA4234 OPA234 OPA2234 OPA4234 SBOS055A – MAY 1996 – REVISED JUNE 2004 Low-Power, Precision SINGLE-SUPPLY OPERATIONAL AMPLIFIERS FEATURES q WIDE SUPPLY RANGE: Single Supply: VS = +2.7V to +36V Dual Supply: VS = ±1.35V to ±18V q SPECIFIED PERFORMANCE: +2.7V, +5V, and ±15V q LOW QUIESCENT CURRENT: 250µA/amp q LOW INPUT BIAS CURRENT: 25nA max q LOW OFFSET VOLTAGE: 100µV max q HIGH CMRR, PSRR, and AOL q 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. The OPA234 series op amps operate from either single or dual supplies. In single-supply operation, the input common-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...
