14MHz, MUX-Friendly, Low-noise, Zero-Drift, RRO, CMOS Precision Operational Amplifier	 - OPA189
 

Description

The OPAx189 (OPA189 and OPA2189) 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 and controlled startup system. These features and excellent ac performance, combined with only 0.4 µV of offset voltage and 0.005 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 input 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.
