3 Description

The OPA2186 is a low-power, 24-V, rail-to-rail input

and output zero-drift operational amplifier (op amp).

This amp features only 8 μV of offset voltage

(max) and 0.04 μV/°C of offset voltage drift over

temperature (max). This device is a great choice for

precision instrumentation, signal measurement, and

active filtering applications.

Low quiescent current consumption (90 μA) makes

the OPA2186 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. This device

also provides robust ESD protection during shipment,

handling, and assembly.
