OPA991QDBVRQ1 General Description

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 or output, low offset (±125 µV, typical), low offset drift (±0.3 µV/°C, typical), 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.
