Description for the OPA2991-Q1

The OPAx991-Q1 family (OPA991-Q1, OPA2991-Q1, and OPA4991-Q1) is a family of high voltage(40-V) general purpose operational amplifiers for automotive application. These devices offerexceptional DC precision and AC performance, including rail-to-rail input/output, low offset (±125µV, typ), low offset drift (±0.3 µV/°C, typ), low noise (10.5 nV/√Hz and 1.8µVPP), and 4.5-MHz bandwidth.

Unique features such as differential and common-mode input-voltage range to the supplyrail, high output current (±75 mA), high slew rate (21 V/µs), high capacitive load drive (1 nF),and shutdown functionality make the OPAx991-Q1 a robust, high-performance operational amplifier forhigh-voltage automotive applications.

The OPAx991-Q1 family of op amps is available in standard packages (such as SOT-23, SOIC,VSSOP, and TSSOP), and is specified from –40°C to 125°C.
