3 Description
The OPA189 and OPA2189 (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.
