Product Summary

The OPA277U is a precision op amp. It replaces the industry standard OP-177. The OPA277U offers improved noise, wider output voltage swing, and are twice as fast with half the quiescent current. Features include ultra low offset voltage and drift, low bias current, high common-mode rejection, and high power supply rejection. Single, dual, and quad versions have identical specifications for maximum design flexibility. The applications of the OPA277U include transducer amplifier, bridge amplifier, temperature measurements, strain gage amplifier, precision integrator, battery powered instruments and test equipment.
