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.
