Notes:
1.
Absolute maximum ratings are the extreme limits the device will withstand without damage to the device. However, the
electrical and mechanical characteristics are not guaranteed as the maximum limits (above recommended operating
conditions) are approached, nor will the device necessarily operate at absolute maximum ratings.

Notes:
1.
Over operating temperature and voltage range unless otherwise noted.
2.
Operate point is defined as the gauss level above which the internal circuitry will always be indicating the presence of a
south pole at the IC surface.
3.
Release point is defined as the gauss level below which the internal circuitry will always be indication the presence of a
north pole at the IC surface.
