Ultralow Offset Voltage: 10 ?V Unlike most operational amplifiers which are specified ? Ultralow Drift: ?0.1 ?V/?C at only one supply voltage, the OPAx277 series is ?

High Common-Mode Rejection: 140 dB performance is maintained as the amplifiers swing to ? High Power Supply Rejection: 130 dB their specified limits. Because the initial offset voltage ? Low Bias Current: 1-nA maximum (?20 ?V maximum) is so low, user adjustment is usually not required. However, the single version ?

The OPA340 series rail-to-rail CMOS operational amplifiers are optimized for low-voltage, single-supply operation. Rail-to-rail input and output and highspeed operation make them ideal for driving sampling analog-to-digital (A/D) converters. They are also wellsuited for general purpose and audio applications as well as providing I/V conversion at the output of digital-to-analog (D/A) converters. Single, dual, and quad versions have identical specifications for design flexibility. The OPA340 series operate on a single supply as low as 2.5 V with an input common-mode voltage range that extends 500 mV below ground and 500 mV above the positive supply. Output voltage swing is to within 1 mV of the supply rails with a 100-k? load. These devices offer excellent dynamic response (BW = 5.5 MHz, SR = 6 V/?s), yet quiescent current is only 750 A. Dual and quad designs feature completely independent circuitry for lowest crosstalk and freedom from interaction
