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 mon-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.
