7.7 Analog Output
This configuration is similar to the PWM connection (only three lines including supply are required). With the addition of a lowpass filter at the
PWM output, this configuration produces an analog voltage that is proportional to the angle. This filter can be either passive (as shown in
Figure
invalid, the PWM output will remain at low state and thus the analog output will be 0V. Pins that are not shown may be left open.

7.8 Quadrature A/B/Index Output
The phase shift between channel A and B indicates the direction of the magnet movement. Channel A leads channel B at a clockwise rotation of
the magnet (top view) by 90 electrical degrees. Channel B leads channel A at a counter-clockwise rotation.
