GENERAL DESCRIPTION

The AD8555 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 AD8555 also accurately amplifies many other differential or single-ended sensor outputs. The AD8555 uses the ADI patented low noise auto-zero and DigiTrim? technologies to create an incredibly accurate and flexible signal processing solution in a very compact footprint.
