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.
