I am reviewing the component sizing for the MC3371B NTC thermistor input filters, following the MC3311B datasheet, section 13.2.5. When I use the provided component values from Table 99 with the equations 17-20 to find the signal cutoff frequency, I find the bandwidth result to be much larger than the bandwidth calculated for the cell voltage measurements.
Temperature signal cutoff frequency calculation:
Cell voltage signal cutoff frequency calculation:
The datasheet notes that these bandwidths should be equal. Is there a problem with my calculations or the values I am using?
