8.2.10 Noise Suppressor

The noise suppressor is inserted after the angle calculation (first stage) and after range expansion (second stage). This function is capable to

reduce the noise level down to 1 LSB peak to peak over different programing ranges.

4 possible configurations of the noise suppressor can be selected via the OTP bits FILTERCFG<1:0>.

8.2.11 Hysteresis Function

AS5162 device includes a hysteresis function to avoid sudden jumps from CLH to CLL and vice versa caused by noise in the full turn

configuration.

The hysteresis amplitude can be selected via the OTP bits HYSTSEL<1:0>.
