Application Notes
After-saturation effects are important in understanding how the sensor behaves. It is important to note
that after the sensor is saturated by a magnetic field, either in the positive or negative direction, it
returns to zero field along the inside curve of the major loop characteristic. As shown in the diagram
below, a negative saturating field applied to the sensor, followed by a small positive field, will result in
a negative voltage output:

After returning to zero,
a small positive field will
cause the output voltage
to go negative

The same small positive field, applied after a positive saturating field, will result in a positive voltage
output:
