Texas Instruments  OPA189IDR

The OPAx189 (OPA189 and OPA2189) series of high-precision operational amplifiers areultra-low noise, fast-settling, zero-drift devices that provide rail-to-rail output operation andfeature a unique MUX-friendly architecture and controlled start-up system. These features andexcellent ac performance, combined with only 0.4 µV of offset voltage and 0.005 µV/°Cof drift over temperature for the single-channel version, make the OPAx189 a great choice forprecision instrumentation, signal measurement, and active filtering applications. Moreover, theMUX-friendly input architecture prevents inrush current when applying large input differentialvoltages which improves settling performance in multi-channel systems, all while providing robustESD protection during shipment, handling, and assembly. All versions are specified from –40°C to+125°C.
