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 ±0.7º (refer to
a centered magnet is between 1.0 – 1.5º (spec = 2º over full temperature range). Within a radius of 0.5mm, the accuracy is better than 2.0º (spec
= 3º over temperature).
