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.
