Product Description

The AD8420ARMZ is a 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. It is based on indirect current feedback architecture that gives it an excellent input common-mode range. Unlike conventional instrumentation amplifiers, the AD8420 can easily amplify signals at or even slightly below ground without requiring dual supplies. The output voltage swing is completely independent of the input common-mode voltage. Single-supply operation, micropower current consumption and rail-to-rail output swing make it ideal for battery powered applications. Its rail-to-rail output stage maximizes dynamic range when operating from low supply voltages. Dual supply operation (±15V) and low power consumption make it ideal for a wide variety of applications in medical or industrial instrumentation.
