OPA2277U Description

The industry standard OP-177 has been replaced by the precision operational amplifiers of the OPA2277U series. They have better noise characteristics, a larger output voltage swing, and twice the speed with half the quiescent current. Ultralow offset voltage, drift, bias current, strong common-mode rejection, and power supply rejection are among the features. For optimum design flexibility, the single, dual, and quad models have identical specs.
