In general, it is possible to program different values of SF and
AF in the ADCFLT register and achieve the same ADC update
rate. However, in practical terms, users should consider the trade-
off between frequency response and ADC noise for any value of
ADCFLT. For optimum filter response and ADC noise when
using combinations of SF and AF, best practice suggests choosing
an SF in the range of 16 decimal to 40 decimal, or 0x10 to 0x28,
and then increasing the AF value to achieve the required ADC
throughput. Table 43 provides information about some common
ADCFLT configurations.
