Hysteresis
The AM512B uses an electrical hysteresis when converting analogue signals to digital. The hysteresis
prevents the flickering of the digital output at a stationary magnet position. The effect is a position hysteresis
when rotating the magnet CW or CCW.

* The hysteresis depends on the signal amplitude. A higher amplitude means a lower hysteresis.
Position delay
At high rotational speed a position delay between the magnet position and the electrical output appears
because of filtering. Filtering is carried out with an RC filter. The value of the resistor is 10 k and the
recommended value of the capacitor is 10 nF. Position delay can be calculated as follows:

Nonlinearity
Nonlinearity is defined as the difference between the actual angular position of the magnet and the angular
position output from the AM512B. Readings are compared at each output position change.
Integral nonlinearity is the total position error of the AM512B output. Figure 16 (page 12) shows a typical
error plot if the recommended magnet is carefully positioned. Figure 17 (page 12) shows the error plot if the
magnet is on the limit of alignment tolerances. Integral nonlinearity includes magnet misalignment error,
differential nonlinearity and transition noise.
Differential nonlinearity is the difference between the measured position step and the ideal position step.
Figure 18 (page 12) shows a typical differential nonlinearity plot. This is a function of the interpolator
accuracy. Differential nonlinearity is repeatable to the transition noise if it is re-measured.
The difference between two differential measurements represents the transition noise. Transition noise is a
consequence of electrical noise in the analogue signals (see Figure 19 on page 12).
