SBOS830A – SEPTEMBER 2017 – REVISED NOVEMBER 2017 OPAx189 Precision, Lowest-Noise 36-V, Zero-Drift, 14-MHz
MUX-Friendly, Rail-to-Rail Output, Operational Amplifiers
1 Features 3 Description The OPAx189 (OPA189 and OPA2189) series of
high-precision operational amplifiers are ultra-low
noise, fast-settling, zero-drift devices that provide railto-rail output operation and feature a unique MUXfriendly architecture and controlled startup system.
These features and excellent ac performance,
combined with only 0.4 ВµV of offset voltage and 0.005
ВµV/В°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 –40В°C to +125В°C. Ultra-High Precision: …
