OPA991-Q1

OPA2991-Q1, OPA4991-Q1 SBOSA12B – MARCH 2020 – REVISED MARCH 2021 OPAx991-Q1 Automotive, 40-V Rail-to-Rail Input/Output, Low Offset Voltage, Low Noise Op Amp 1 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 nV/√ Hz at 1 kHz High common-mode rejection: 130 dB Low bias current: ±10 pA 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 nV/√ Hz and 1.8 µVPP), and 4.5-MHz bandwidth. Unique features such as differential and commonmode 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 OPAx991Q1 a robust, high-performance operational amplifier High capacitive load drive: 1 nF for high-voltage automotive applications. MUX-friendly/comparator inputs – Amplifier operates with differential inputs up to supply rail – Amplifier can be used in open-loop or as comparator Low...
