The OPA189 and OPA2189 (OPAx189) high-precision operational amplifiers are ultra-lownoise, fast-settling, zero-drift devices that provide rail-to-rail output operation and feature aunique MUX-friendly architecture and controlled start-up system. These features and excellent acperformance, combined with only 0.4 µV of offset voltage and 0.005µV/°C of drift overtemperature for the single-channel version, make the OPAx189 a great choice for precisioninstrumentation, signal measurement, and active filtering applications. Moreover, the MUX-friendlyinput architecture prevents inrush current when applying large input differential voltages, whichimproves settling performance in multichannel systems, all while providing robust ESD protectionduring shipment, handling, and assembly.

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