Figure 26. Vertical Magnetic Fields of a Rotating Magnet
Magnet Placement
Ideally, the center of the magnet, the diagonal center of the IC and the rotation axis of the magnet should be in one
vertical line. The lateral displacement of the magnet should be within +/-0.25mm from the IC package center or +/-
0.5mm from the IC center, including the placement of the chip within the IC package. The vertical 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 1.8mm with the recommended magnet (6mm x 2.5mm). Larger gaps
are possible, as long as the required magnetic field strength stays within the defined limits. A magnetic field outside the
specified range may still produce acceptable results, but with reduced accuracy. The out-of-range condition will be
indicated, when the AGC is at the limits (AGC= 0 : field too strong; AGC=63=(3F
