Overview

The OPAx189 (OPA189 and OPA2189) series precision op-amps feature ultra-low noise, fast settling time, and zero temperature drift, with rail-to-rail output operation, a unique MUX-friendly architecture, and a controlled turn-on system. These characteristics, combined with excellent AC performance, an offset voltage of only 0.4μV, and temperature drift of 0.005μV/°C, make the OPAx189 ideal for high-precision instrumentation, signal measurement, and active filter applications. Additionally, the MUX-friendly input architecture prevents surge currents when large differential input voltages are applied, improving settling time performance in multi-channel systems while providing robust ESD protection during shipping, handling, and assembly. All device versions are rated for an operating temperature range of -40°C to +125°C.
