OPA4990D Datasheet Low-power Op-Amp

Manufacturer: Texas Instruments

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

OPA4990D Overview

The OPAx990 family (OPA990, OPA2990, and OPA4990) is a family of high voltage (40-V) general purpose operational amplifiers. These devices offer excellent DC precision and AC performance, including rail-to-rail input/output, low offset (±300 µV, typ), and low offset drift (±0.6 µV/°C, typ).

OPA4990D Key Features

  • 1 Low offset voltage: ±300 µV
  • Low offset voltage drift: ±0.6 µV/°C
  • Low noise: 30 nV/√Hz at 1 kHz
  • High mon-mode rejection: 115 dB
  • Low bias current: ±10 pA
  • Rail-to-rail input and output
  • MUX-friendly/parator inputs
  • Amplifier operates with differential inputs up to supply rail
  • Amplifier can be used in open-loop or as parator
  • Wide bandwidth: 1.1-MHz GBW
