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 bandwidth
• A multiplier amplifies the value depending on the gain (see
• The offset value is added (see
• A limiter reduces the resulting signal to 16 bits (see
Temperature Compensation
(Details are listed in
• The output signal of the temperature cell is also A/D converted

in the continuous-time A/D converter. The range of the chopped A/D converter can be
set in several steps either by EEPROM settings or dynamically by the master in the
dynamic range mode (see
