The AAV003-10E GMR current sensor from NVE is a high linearity, extremely low hysteresis sensor with an on-chip current strap. The GMR bridge has a supply voltage of +24V with the sensor element being situated close to the current strap and senses the magnetic field created by the current. The AAV sensor from NVE has a linear range of -0.08mA to +0.08mA and uses a unique bipolar output with a low hysteresis GMR material for excellent accuracy. The four terminals of the GMR bridge sensor are available externally and the output terminals of the bridge provide a bipolar voltage signal proportional to the current through the strap.

The below table gives the full specifications of the NVE AAV003-10E
1. For isolation measurement, the sensor is considered a two terminal device: I+ and I- pins (pins 3 and 4) are shorted, and bridge pins (pins 1, 2, 5, and 6) are shorted.
2. TCOV is the percent change in output signal over temperature, with a constant voltage source powering the part.
