SBOS701D – DECEMBER 2015 – REVISED AUGUST 2021

OPAx191 36-V, Low-Power, Precision, CMOS, Rail-to-Rail Input/Output,

Low Offset Voltage, Low Input Bias Current Op Amp

1 Features

3 Description

•

Low offset voltage: ±5 µV

The OPAx191 family (OPA191, OPA2191, and

OPA4191) is a new generation of 36-V, e-trim^™

operational amplifiers.

Low offset voltage drift: ±0.1 µV/°C

Low noise: 15 nV/√ Hz at 1 kHz

High common-mode rejection: 140 dB

Low bias current: ±5 pA

Rail-to-rail input and output

Wide bandwidth: 2.5-MHz GBW

High slew rate: 5 V/µs

Low quiescent current: 140 µA per amplifier

Wide supply: ±2.25 V to ±18 V, 4.5 V to 36 V

EMI/RFI filtered inputs

Differential input voltage range to supply rail

High capacitive load drive capability: 1 nF

Industry standard packages:

These devices offer outstanding dc precision and

ac performance, including rail-to-rail input/output, low

offset voltage (±5 µV, typ), low offset drift (±0.2 µV/°C,

typ), and 2-MHz bandwidth.

Unique features, such as differential input-voltage

range to the supply rail, high output current (±65 mA),

high capacitive load drive of up to 1 nF, and high

slew rate (5 V/µs), make the OPAx191 a robust, high-

performance operational amplifier for high-voltage

industrial applications.

– Single in SOIC-8, SOT-5, and VSSOP-8

– Dual in SOIC-8 and VSSOP-8

– Quad in SOIC-14, TSSOP-14, and WQFN-16

The OPAx191 family of op amps is available in

standard packages and is specified from –40°C to

+125°C.
