Product Description

The OPAx189 (OPA189, OPA2189, and OPA4189) series of 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. These features and excellent ac performance, combined with only 0.4 µV of offset and 0.0035 µV/°C of drift over temperature, makes the OPAx189 well-suited for precision instrumentation, signal measurement, and active filtering applications. Moreover, the MUX-friendly input architecture prevents inrush current when applying large differential voltages which improves settling performance in multi-channel systems, all while providing robust ESD protection during shipment, handling, and assembly. All versions are specified from –40°C to +125°C.
