AD8556ARZ-REEL7

Overview

The AD8556ARZ-REEL7 is a zero-drift sensor signal amplifier with digitally programmable gain and output offset. It operates from a single supply of 4.5 V to 5.5 V. The device features low input offset voltage (10 µV maximum) and low drift (65 nV/°C). Gain is programmable from 70 to 1280 via a serial interface. It includes EMI filters, open/short wire fault detection, and a programmable output clamp.

Feature Summary

• Digitally programmable gain and output offset voltage
• Integrated EMI filters at input pins
• Open and short wire fault detection capabilities
• Programmable output clamp voltage

Applications

• Pressure sensors
• Position sensors
• Precision current sensing
• Strain gages

Procurement Notes
