GENERAL DESCRIPTION
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.
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 (±15 V) and low power consumption make
the AD8420 ideal for a wide variety of applications in medical
or industrial instrumentation.
The AD8420 is available in an 8-lead MSOP package. Performance
is specified over the full temperature range of 40°C to +85°C,
and the part is operational from 40°C to +125°C.
