AAV003-10E is a highly linear, 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. The bridge output voltage is bipolar and
proportional to the current through the strap.
Typical sensitivity is a remarkable 2 mV/mA with a 24 V supply and no amplification.Key specifications are summarized as follows:
