A digital low-pass filter is placed between the Hall A/D converter and the DSP an can be
to reduce the noise level. The low-pass filter has a constant DC amplification of 0 dB
(gain of 1), which means that its setting has no influence on the internal Hall A/D
converter value.
The bandwidth can be set in 8 steps.
