Note 9. The passband and stopband frequencies scale with fs.

For example, PB=18.9kHz@

±0.1dB is 0.39375 × fs.

Note 10. The calculated delay time induced by digital filtering. This time is from the input of an analog signal to the

setting of 24bit data both channels to the ADC output register for ADC.
