AD8556ARZ

The AD8556ARZ is a zero-drift Sensor Signal Amplifier with digitally programmable gain, output offset and EMI filters. Designed to easily and accurately convert variable pressure sensor and strain bridge outputs to a well-defined output voltage range, the AD8556ARZ accurately amplifies many other differential or single-ended sensor outputs. The AD8556ARZ 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. Gain is digitally programmable in a wide range from 70 to 1280 through a serial data interface. Gain adjustment can be fully simulated in-circuit and then permanently programmed with reliable polyfuse technology. Output offset voltage is also digitally programmable and is ratiometric to the supply voltage. The AD8556ARZ also features internal EMI filters on the VNEG, VPOS, FILT and VCLAMP pins.
