8.2.3 Physical Placement of the Magnet
The best linearity can be achieved by placing the center of the magnet exactly over the defined center of the chip as shown in
Figure
26.

8.2.4 Magnet Placement
The magnet’s center axis should be aligned within a displacement radius R
of 0.25mm (larger magnets allow more displacement) from the
d
defined center of the IC.
The magnet may be placed below or above the device. The distance should be chosen such that the magnetic field on the die surface is within
the specified limits
(see Figure
26). The typical distance “z” between the magnet and the package surface is 0.5mm to 1.5mm, provided the
recommended magnet material and dimensions (6mm x 3mm) are used. Larger distances are possible, as long as, the required magnetic field
strength stays within the defined limits.
However, a magnetic field outside the specified range may still produce usable results, but the out-of-range condition will be indicated by an
alarm forcing the output into the failure band.
