AD8556ACPZ-REEL7

AD8556ACPZ-REEL7 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, it 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 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 supply voltage. It features internal EMI filters on the VNEG, VPOS, FILT and VCLAMP pins. Typical applications include pressure and position sensors, precision current sensing and strain gages.
