Figure 11. Simple Passive 2 Order Lowpass Filter
7.4 Analog Output
An analog output may be generated by averaging the PWM signal, using an external active or passive lowpass filter. The analog output voltage
is proportional to the angle: 0o = 0V; 360o = VDD5V. Using this method, the AS5140H can be used as direct replacement of potentiometers.

(EQ 3)
R1 should be ≥ 4k7 to avoid loading of the PWM output. Larger values of Rx and Cx will provide better filtering and less ripple, but will also slow
down the response time.
