Three (3) differential voltages corresponding to the three (3) components of the applied flux density are
provided to the ADC (Analog-to-Digital Converter – Figure 8 and Figure 9). The 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 amplitude of V
gain of the IMC only affects the components parallel to the IC surface.
