AD8420 Datasheet (Analog Devices) - Rail-to-Rail Output Instrumentation Amplifier

AD8420, Rail-to-Rail Output Instrumentation Amplifier

The AD8420 is a low cost, micropower, wide supply range, instrumentation amplifier with a rail-to-rail output and a novel architecture that allows for extremely flexible design.

It is optimized to amplify small differential voltages in the presence of large common-mode signals.

The AD8420 is based o
