GENERAL DESCRIPTION

Single-supply operation, micropower current consumption, and

rail-to-rail output swing make the AD8420 ideal for battery-

powered applications. Its rail-to-rail output stage maximizes

dynamic range when operating from low supply voltages. Dual-

supply operation (±±1 ꢀV and low power consumption make

the AD8420 ideal for a wide variety of applications in medical

or industrial instrumentation.

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 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 AD8420 has rail-to-rail output, and the output

voltage swing is completely independent of the input common-

mode voltage.

The AD8420 is available in an 8-lead MSOP package. Performance

is specified over the full temperature range of −40°C to +81°C,

and the part is operational from −40°C to +±21°C.
