OPA4277 - High Precision Operational Amplifier

This page provides the datasheet information for the OPA4277, a member of the OPA2277 High Precision Operational Amplifier family.

Datasheet Summary

Description

The OPAx277 series of precision operational amplifiers replace the industry standard OP-177.

The OPAx277 devices offer improved noise, wider output voltage swing, and are twice as fast with half the quiescent current.

Features

Ultra-low offset voltage: 10 μV.
Ultra-low drift: ±0.1 μV/°C.
High open-loop gain: 134 dB.
High common-mode rejection: 140 dB.
High power-supply rejection: 130 dB.
Low bias current: 1-nA maximum.
Wide supply range: ±2 V to ±18 V.
Low quiescent current: 800 μA/amplifier.
Single, dual, and quad versions.
Replaces OP-07, OP-77, and OP-177.
For similar performance with ±40-V overvoltage protection, se.
