AD8557ARZ

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. It is suitable for use in automotive sensors, pressure and position sensors, precision current sensing, thermocouple amplifiers, industrial weigh scales, strain gauges applications.
