OPAx991 40-V Rail-to-Rail Input/Output, Low Offset Voltage, Low Noise Op Amp

1 Features

3 Description

•

Low offset voltage: ±125 µV

The OPAx991 family (OPA991, OPA2991, and

OPA4991) is a family of high voltage (40-V) general

purpose operational amplifiers. 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 (10.5

nV/√ Hz and 1.8 µV_PP), and 4.5-MHz bandwidth.

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

High capacitive load drive: 1 nF

MUX-friendly/comparator inputs

– Amplifier operates with differential inputs up to

supply rail

– Amplifier can be used in open-loop or as

comparator

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

Differential and common-mode input voltage range

to supply rail

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),

high capacitive load drive (1 nF), and shutdown

functionality make the OPAx991 a robust, high-

performance operational amplifier for high-voltage

industrial applications.

•

The OPAx991 family of op amps is available in

micro-size packages (such as X2QFN, WSON, and

SOT-553), as well as standard packages (such as

SOT-23, SOIC, and TSSOP), and is specified from

–40°C to 125°C.
