8.9.2 Lateral Displacement of the Magnet
As shown in the magnet specifications
center is within a circle of 0.25mm radius. This includes the placement tolerance of the IC within the package.
Figure 34
The X- and Y- axis of the graph indicate the lateral displacement of the magnet center with respect to the IC center.
At X = Y = 0, the magnet is perfectly centered over the IC. The total displacement plotted on the graph is for ± 1mm in both directions.
The Z-axis displays the worst case INL error over a full turn at each given X-and Y- displacement. The error includes the quantization error of ±
0.7°. For example, the accuracy for a centered magnet is between 1.0 ~ 1.5° (spec = 2° over full temperature range). Within a radius of 0.5mm,
the accuracy is better than 2.0° (spec = 3° over temperature).
