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.
