Data Sheet
9.1 Changing the PWM Frequency
The PWM frequency of the AS5045 can be divided by two by setting a bit (PWMhalfEN) in the OTP register (see
chapter 11). With PWMhalfEN = 0 the PWM timing is as shown in Table 6 :

10 Analog Output
An analog output can be generated by averaging the PWM signal, using an external active or passive low pass filter.
The analog output voltage is proportional to the angle: 0°= 0V; 360° = VDD5V.
Using this method, the AS5045 can be used as direct replacement of potentiometers.

Order Passive RC Low Pass Filter
Figure 9 shows an example of a simple passive low pass filter to generate the analog output.
R1, R2 ≥ 4k7
C1, C2 ≥ 1μF / 6V
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.
