Note 8. The passband and stopband frequencies scale with fs. For example, PB (

±0.02dB) at fs=48kHz is 0.4535 × fs. The

reference frequency of these response is 1kHz.

Note 9. 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.
