Product Summary

The OPA4277PA precision op amp replaces the industry standard OP-177. It offers improved noise, wider output voltage swing, and is twice as fast with half the quiescent current. Features of OPA4277PA 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 OPA4277PA include transducer amplifier, bridge amplifier, temperature measurements, strain gage amplifier, precision integrator, battery powered instruments, test equipment.
