OPA991-Q1 is Low Noise Op Amp manufactured by Texas Instruments.
Features 3 Description - AEC-Q100 qualified for automotive applications The OPAx991-Q1 family (OPA991-Q1, OPA2991-Q1, - Temperature grade 1: - 40°C to +125°C, TA - Device HBM ESD classification level 2A - Device CDM ESD classification level C6 - Low offset voltage: ±125 µV - Low offset voltage drift: ±0.3 µV/°C - Low noise: 10.8 n V/√ Hz at 1 k Hz - High mon-mode rejection: 130 d B - Low bias current: ±10 p A - Rail-to-rail input and output - Wide bandwidth: 4.5 MHz GBW - High slew rate: 21 V/µs 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 n V/√ Hz and 1.8 µVPP), and 4.5-MHz bandwidth. Unique features such as differential and monmode input-voltage range to the supply rail, high output current (±75 m A), high slew rate (21 V/µs), and high capacitive load drive (1 n F) make the OPAx991Q1 a robust, high-performance operational amplifier - High capacitive load drive: 1 n F for high-voltage automotive applications. - MUX-friendly/parator inputs - Amplifier operates with differential inputs up to supply rail - Amplifier can be used in open-loop or as parator - 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 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.
