18 / 39 page TLE4998S Signal Processing Data Sheet 18 V 1.0, 2008-07 6 Signal Processing The signal flow diagram in Figure 6 shows the signal path and data-processing algorithm. Figure 6 Signal Processing Flow Magnetic Field Path • The analog output signal of the chopped Hall-effect cell is converted to a digital signal in the continuous-time A/D converter. The range of the chopped A/D converter can be set in several steps (see Table 7). This gives a suitable level for the A/D converter • After the A/D conversion, a digital low-pass filter reduces the bandwidth (Table 11) • A multiplier amplifies the value depending on the gain (see Table 9) and temperature compensation settings • The offset value is added (see Table 10) • A limiter reduces the resulting signal to 16 bits (see Chapter 13) and feeds the Protocol Generation stage Temperature Compensation (Details are listed in Chapter 8) • The output signal of the temperature cell is also A/D converted Stored in EEPROM Memory + X A D Hall Sensor Limiter (Clam p) out X Range LP Offset Gain A D + -T0 TC1 Temperature Compensation 1 + X TC2 X X Protocol Generation Temperature Sensor |
