Description

The OPAx991-Q1 family (OPA991-Q1, OPA2991-Q1, and OPA4991-Q1) is a family of high voltage (40V) general purpose operational amplifiers for automotive application. These devices offer exceptional DC precision and AC performance, including rail-to-rail input or output, low offset (±125µV, typical), low offset drift (±0.3µV/°C, typical), low noise (10.8nV/√Hz and 1.8µVPP), and 4.5MHz bandwidth. Unique features such as differential and common-mode input-voltage range to the supply rail, high output current (±75mA), high slew rate (21V/µs), and high capacitive load drive (1nF) make the OPAx991-Q1 a robust, high-performance operational amplifier for high-voltage automotive applications. The OPAx991-Q1 family of op amps is available in standard packages (such as SOT-23, SC70, SOIC, VSSOP, and TSSOP) and is specified from –40°C to 125°C.
