3 Description

The OPAx189 (OPA189 and OPA2189) family of precision operational amplifiers features ultra-low noise, fast settling time, and zero temperature drift, provides rail-to-rail output operation, and features a unique MUX-friendly architecture and controlled startup system. These features and excellent AC performance, along with an offset voltage of only 0.4 μV and a temperature drift of 0.005 μV/°C, make the OPAx189 ideal for high-precision instrumentation, signal measurement, and active filtering applications. Additionally, the MUX-friendly input architecture prevents inrush current when large input differential voltages are applied, improving settling time performance in multi-channel systems, while also providing robust ESD protection during shipping, operation, and assembly . All device versions are specified over a temperature range of -40°C to +125°C.
