OPAx990 40-V Rail-to-Rail Input/Output, Low Offset Voltage, Low Power Op Amp

1 Features

3 Description

•

Low offset voltage: ±300 µV

The OPAx990 family (OPA990, OPA2990, and

OPA4990) is a family of high voltage (40-V) general

purpose operational amplifiers. These devices offer

excellent DC precision and AC performance, including

rail-to-rail input/output, low offset (±300 µV, typ), and

low offset drift (±0.6 µV/°C, typ).

Low offset voltage drift: ±0.6 µV/°C

Low noise: 30 nV/√Hz at 1 kHz

High common-mode rejection: 115 dB

Low bias current: ±10 pA

Rail-to-rail input and output

MUX-friendly/comparator inputs

– Amplifier operates with differential inputs up to

supply rail

– Amplifier can be used in open-loop or as

comparator

Unique features such as differential and common-

mode input voltage range to the supply rail, high

short-circuit current (±80 mA), high slew rate (4.5 V/

µs), and shutdown make the OPAx990 an extremely

flexible, robust, and high-performance op amp for

high-voltage industrial applications.

•

Wide bandwidth: 1.1-MHz GBW

High slew rate: 4.5 V/µs

The OPAx990 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.

Low quiescent current: 120 µA per amplifier

Wide supply: ±1.35 V to ±20 V, 2.7 V to 40 V

Robust EMIRR performance: 78 dB at 1.8 GHz

Differential and common-mode input voltage range

to supply rail
