AD8420 datasheet



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 on an indirect current feedback architecturethat gives it an excellent input common-mode range. Unlike conventional instrumentation amplifiers, the AD8420can easily amplify signals at or even slightly below ground without requiring dual supplies. The AD8420 has rail-to-rail output, and the output voltage swing is completely independent of the input common mode voltage.
