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 offer exceptional DC

precision and AC performance, including rail-to-rail

input/output, low offset (±125 µV, typ), low offset drift

(±0.3 µV/°C, typ), low noise (10.8 nV/√Hz and 1.8

µV_PP), and 4.5-MHz bandwidth.

•

Unique features such as differential and common-

mode input-voltage range to the supply rail, high

output current (±75 mA), high slew rate (21 V/µs), and

high capacitive load drive (1 nF) 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, SOIC, VSSOP,

and TSSOP) and is specified from –40°C to 125°C.

•

Low quiescent current: 560 µA per amplifier

Wide supply: ±1.35 V to ±20 V, 2.7 V to 40 V

Robust EMIRR performance: EMI/RFI filters on

input and supply pins
