OPA4277 Datasheet High Precision Operational Amplifier

Manufacturer: Texas Instruments

Overview: OPA277, OPA2277, OPA4277 SBOS079C – MARCH 1999 – REVISED FEBRUARY 2023 OPAx277 High-Precision Operational Amplifiers 50nV/div.

This datasheet includes multiple variants, all published together in a single manufacturer document.

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.
