These op amps feature only 10 µV of offset voltage (maximum) and 0.
04 µV/°C of offset voltage drift over temperature (maximum).
These devices are a great choice for precision instrumentation, signal measurement, and active-filtering applications.
The low quiescent current consumption of 90 μA makes the OPAx186 an excellent option for powersensitive applications, such as battery-powered instrumentation and portable systems.
Moreover, the high common-mode architecture along with low offset voltage allows for high-side current shunt monitoring at the positive rail.
These devices also provide robust ESD protection during shipment, handling, and assembly.
