OPA4277 - High Precision Operational Amplifier

Download the OPA4277 datasheet PDF. This datasheet also covers the OPA2277 variant, as both devices belong to the same high precision operational amplifier family and are provided as variant models within a single manufacturer datasheet.

General 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.

Key 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.
