Magnetic Field Path
• The analog output signal of the chopped Hall-effect cell is converted to a digital signal
• After the A/D conversion, a digital-low pass filter reduces the band width
• A multiplier amplifies the value depending on the gain (see
• The offset value is added (see
• A limiter reduces the resulting signal to 12 bits and feeds the Protocol Generation
Temperature Compensation
(Details are given in
• The output signal of the temperature cell is also A/D converted
• The temperature is normalized by subtraction of the reference temperature T
