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 VZ is smaller than the other two (2) components VX and VY due to fact that the magnetic
gain of the IMC only affects the components parallel to the IC surface.
