DESCRIPTION
The OPAx277 series precision operational amplifiers replace the industry standard OP-177. They offer improved noise, wider output voltage swing, and are twice as fast with half the quiescent current. Features include ultralow offset voltage and drift, low bias current, high common-mode rejection, and high 0.1 Hz to 10 Hz Noise power supply rejection. Single, dual, and quad versions have identical specifications, for maximum
design flexibility.
