Those Hall signals are processed through a fully differential analog chain featuring the classic offset
cancellation technique (Hall plate quadrature spinning and chopper-stabilized amplifier).
The conditioned analog signals are converted through an ADC (configurable
to a DSP block for further processing. The DSP stage is based on a 16 bit RISC micro-controller whose
primary function is the extraction of the angular position from the two raw signals (after so-called front-end
compensation steps) through the following operation:
