Product Summary

The OPA4277UA/2K5 is a high precision operational amplifier. The OPA4277UA precision op amp replaces the industry standard OP-177. It 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 OPA4277UA/2K5 include transducer amplifier, bridge amplifier, temperature measurements, strain gage amplifier, precision integrator, battery powered instruments and test equipment.
