8.10 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 the drawing below:
Figure 35. Defined Chip Center and Magnet Displacement Radius
Magnet Placement.
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. The typical distance “z” between the magnet and the package surface is 0.5mm to 1.5mm, provided the use of the
recommended magnet material and dimensions (6mm x 3mm). 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
MagRngn (pin 1).
