Data Sheet AAV003-10E Current Sensor Key Features - For Low Current Detection - On-Chip Current Strap for Precise Operation - - 80 m A to +80 m A Linear Range - Sensitivity up to 2 m V/m A - AC or DC Measurement - Ultraminiature TDFN Package Description The AAV003-10E is a high linearity, extremely low hysteresis GMR current sensor with an on-chip current strap. A GMR bridge sensor element close to the current strap senses the magnetic field created by the current. The GMR sensor element uses a unique, bipolar output, low hysteresis GMR material for excellent accuracy. The four terminals of the bridge sensor are available externally. The output terminals of the bridge provide a bipolar voltage signal proportional to the current through the strap.
