Description

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.

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