Data Sheet
Figure 21. Example of Linearity Error over XY Misalignment
The maximum non-linearity error on this example is better than ±1 degree (inner circle) over a misalignment radius of
~0.7mm. 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 ±1.4 degrees.
The magnet used for this measurement was a cylindrical NdFeB (Bomatec® BMN-35H) magnet with 6mm diameter
and 2.5mm in height.
