7.8 Analog Output

This configuration is similar to the PWM connection (only three lines including supply are required). With the addition of a low-pass 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) or active. The lower the bandwidth of the filter, the less ripple of the analog output can be achieved.

If the AS5030 angular data is 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.

Note:

The PWM output is invalid when the AGC is disabled.
