Overview
Data Sheet FEATURES Very low offset voltage: 12 μV maximum over temperature Very low input offset voltage drift: 65 nV/°C maximum High CMRR: 96 dB minimum Digitally programmable gain and output offset voltage Gain range from 28 to 1300 Qualified for automotive applications Single-wire serial interface Stable with any capacitive load SOIC and LFCSP packages 2.
7 V to 5.
5 V operation APPLICATIONS Automotive sensors Pressure and position sensors Precision current sensing Thermocouple amplifiers Industrial weigh scales Strain gages GENERAL DESCRIPTION The 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.
The AD8557 uses the Analog Devices, Inc.
, proprietary low noise auto-zero and DigiTrim® technologies to create an accurate...
