AD8557 Datasheet Digitally Programmable Sensor Signal Amplifier

Manufacturer: Analog Devices

General Description

The AD8557 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 AD8557 accurately amplifies many other differential or single-ended sensor outputs.

The AD8557 uses the Analog Devices, Inc., proprietary low noise auto-zero and DigiTrim® technologies to create an accurate and flexible signal processing solution in a compact footprint.
