The OPAx990-Q1 family (OPA990-Q1, OPA2990-Q1, and OPA4990-Q1) is a family of high voltage (40V) general purpose operational amplifiers. These devices offer excellent DC precision and AC performance, including rail-to-rail input or output, low offset (±300µV, typ), and low offset drift (±0.6µV/°C, typ).

Unique features such as differential and common-mode input voltage range to the supply rail, high short-circuit current (±80mA), and high slew rate (4.5V/µs) make the OPAx990-Q1 an extremely flexible, robust, and high-performance op amp for high-voltage automotive applications.

The OPAx990-Q1 family of op amps is available in several standard packages (such as, SOT-23, SOIC, and TSSOP) and is specified from –40°C to 125°C.
