AD8555ARZ

产品概述

The 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.
