8.1.2 AMR Output Dependence on Airgap Distance

The AMR sensor is only sensitive to the direction of the applied magnetic field along the X-Y plane parallel to the chip surface. The applied magnetic field from a rotating magnet can vary based on the airgap distance between the TMAG6184 and the magnet.

As long the absolute magnetic field is above the minimum field listed in Recommended Operating Conditions, the angle accuracy from the AMR outputs are independent of the value of the applied magnetic field.
