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).

Unique features such as differential and common-mode input voltage range to the supply rail, high short-circuit current (±80 mA), high slew rate (4.5 V/µs), and shutdown make the OPAx990 an extremely flexible, robust, and high-performance op amp for high-voltage industrial applications.

The OPAx990 family of op amps is available in micro-size packages (such as X2QFN, WSON, and SOT-553), as well as standard packages (such as SOT-23, SOIC, and TSSOP), and is specified from –40°C to 125°C.

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
  • Low quiescent current: 120 µA per amplifier
  • Wide supply: ±1.35 V to ±20 V, 2.7 V to 40 V
  • Robust EMIRR performance: 78 dB at 1.8 GHz
  • Differential and common-mode input voltage range to supply rail
