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 10 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.

The low quiescent current consumption of 90 μA

makes the OPA2186 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. This device

also provides robust ESD protection during shipment,

handling, and assembly.
