The end user must apply a saturating magnetic field (30 to 200 Oersteds) in the plane of the sensor in
order for the sensor to operate. The movable layer will align with the applied magnetic field. As the
applied field changes direction the angle between the movable layer and the pinned layer changes,
resulting in a change of resistance in the device. A graph of the device resistance vs. the angle between
the pinned layer and the movable layer is shown below:
 
Four individual sensor resistors are supplied in the package, each with the pinned layer rotated 90?with
respect to that of the previous sensor. These resistors can be connected in two half-bridge
configurations to provide a sine and cosine output or monitored individually to provide an absolute
indication of the angle between the pinned layer and the movable layer.
