Figure 22. 3D Graph Displaying Non-Linearity Over XY-Misalignment
For volume production, the placement tolerance of the IC within the package (±0.235mm) must also be taken into
account. The total nonlinearity error over process tolerances, temperature and a misalignment circle radius of 0.25mm
is specified better than ±2 degrees.
The magnet used for this measurement is a cylindrical NdFeB (Bomatec® BMN-35H) magnet with 6mm diameter and
2.5mm in height.
Mounting the Magnet
Generally, for on-axis rotation angle measurement, the magnet must be mounted centered over the IC package. How-
ever, the material of the shaft into which the magnet is mounted, is also of big importance.
Magnetic materials in the vicinity of the magnet will distort or weaken the magnetic field being picked up by the Hall
elements and cause additional errors in the angular output of the sensor.
