Texas Instruments' OPA2189 high-precision, ultra-low noise, fast-settling, zero-drift op-amp provides rail-to-rail output operation and features a MUX-friendly architecture and controlled start-up system. These features and excellent AC performance, combined with 0.4 µV of offset voltage and 0.005 µV/°C of drift over temperature for the single-channel version, make the OPA2189 ideal for precision instrumentation, signal measurement, and active filtering applications. The MUX-friendly input architecture prevents inrush current when applying large input differential voltages which improves settling performance in multi-channel systems while providing robust ESD protection during shipment, handling, and assembly. The device is specified over a temperature range of -40°C to +125°C.
