OPA2990 - Low-Power OpAmp

General Description

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).

Key Features

  • Low offset voltage: ±300 µV.
  • Low offset voltage drift: ±0.6 µV/°C.
  • Low noise: 30 nV/√Hz at 1 kHz.
  • High common-mode rejection: 115 dB.
  • Low bias current: ±10 pA.
  • Rail-to-rail input and output.
  • MUX-friendly/comparator inputs.
  • Amplifier operates with differential inputs up to supply rail.
  • Amplifier can be used in open-loop or as comparator.
  • Wide bandwidth: 1.1-MHz GBW.
  • High slew rate: 4.5 V/µs.
