MUX-Friendly, Rail-to-Rail Output Operational Amplifiers

1 Features

3 Description

•

Ultra-high precision:

The OPA189, OPA2189, and OPA4189 (OPAx189)

high-precision operational amplifiers are ultra-low

noise, fast-settling, zero-drift devices that provide rail-

to-rail output operation and feature a unique MUX-

friendly architecture and controlled start-up system.

These features and excellent ac performance,

combined with only 0.4 µV of offset voltage and

0.005µV/°C of drift over temperature for the single-

channel version, make the OPAx189 a great choice

for precision instrumentation, signal measurement,

and active filtering applications. Moreover, the MUX-

friendly input architecture prevents inrush current

when applying large input differential voltages,

which improves settling performance in multichannel

systems, all while providing robust ESD protection

during shipment, handling, and assembly.

– Zero-drift: 0.005 μV/°C (OPA189)

– Ultra-low offset voltage: 3 μV maximum

(OPA189)

Excellent dc precision:

– CMRR: 168 dB

•

– Open-loop gain: 170 dB

Low noise:

– e_nat 1 kHz: 5.2 nV/√Hz

– 0.1-Hz to 10-Hz noise: 0.1 µV_PP

Excellent dynamic performance:

– Gain bandwidth: 14 MHz

– Slew rate: 20 V/µs

– Fast settling: 10-V step, 0.01% in 1.1 µs

Robust design:

– MUX-friendly inputs

– RFI/EMI filtered inputs

Wide supply range: 4.5 V to 36 V

Quiescent current: 1.7 mA (maximum)

Rail-to-rail output

•

All versions are specified from –40°C to +125°C.
