GENERAL DESCRIPTION
The AD8556 is a zero-drift, sensor signal amplifier with digitally programmable gain and output offset. Designed to easily and accurately convert variable pressure sensor and strain bridge outputs to a well-defined output voltage range, the AD8556 accurately amplifies many other differential or single-ended sensor outputs. The AD8556 uses the Analog Devices, Inc. patented low noise, auto-zero and DigiTrim® technologies to create an incredibly accurate and flexible signal processing solution in a very compact footprint.
