AD8555ARZThe AD8555ARZ 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. 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 proven and reliable poly-fuse technology. Output offset voltage is also digitally programmable and is ratiometric to the supply voltage., Digitally programmable gain and output offset voltage, Single-wire serial interface, Open and short wire fault detection, Low-pass filtering, Stable with any capacitive load, Externally programmable output clamp voltage for driving low voltage ADCs, 10µV Maximum over temperature very low offset voltage, 60nV/°C Maximum very low input offset voltage drift, 96dB Minimum high CMRR
