The OPA186, OPA2186, and OPA4186 (OPAx186) are low-power, 24-V, rail-to-rail input and output, zero-drift operational amplifiers (op amps). 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 power-sensitive 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.
