Overview

The OPAx991 series is a high-voltage (40V) general-purpose operational amplifier series. These devices feature excellent DC accuracy and AC performance, including rail-to-rail input/output, low offset voltage (±125μV typ.), low temperature drift (±0.3μV/°C typ.), low noise (10.5nV/√Hz and 1.8μVPP), and a 4.5MHz bandwidth.

Applications

  • Low-power audio preamplifier
  • Multiplexed data acquisition system
  • Test and measurement equipment
  • ADC driver amplifier
  • SAR ADC reference buffer
  • Programmable logic controller
  • High-side and low-side current sensing
  • High-voltage multiplexed data acquisition system

Key features

  • Low offset voltage: ±125μV
  • Low offset voltage drift: ±0.3μV/°C
  • Low noise: 10.8nV/√Hz at 1 kHz
  • High common-mode rejection: 130dB
  • Low bias current: ±10pA
  • Rail-to-rail input and output
  • Wide bandwidth: 4.5MHz GBW
  • High slew rate: 21V/µs
  • High capacitive load drive: 1nF
  • Multiplexer/comparator input support
  • Amplifier operates with differential input up to the supply rail
  • Amplifier usable open-loop or as a comparator
  • Low quiescent current: 560μA per amplifier
  • Wide supply voltage: ±1.35V to ±20V, 2.7V to 40V
  • Robust EMIRR performance: EMI/RFI filters on input and supply pins
  • Differential and common-mode input voltage range up to supply rails
