OP277 High Precision Op-Amp – Datasheet

OP277 series precision op amps replace the industry standard OP-177. The IC has range of working conditions a wide range of working voltages, and possesses direct interfacing capability with almost every PMOS, CMOS, and NMOS device. Moreover, the IC offers a wide array of features such as high noise immunity, ESD barring/reduction, and exceptionally low power dissipation.

Precision Operational Amplifier

Precision amplifiers are op amps with better design specifications in terms of precision offset, zero-drift over time, lower internal noise, and input bias current. These op-amps are used in analog filters where they do not distort or DC offset the signal of interest. Their functionality and mode of use is somewhat similar to conventional op – amps; but, the output is precise, accurate, and virtually free of any kind of noise.
