Note 20. The passband and stopband frequencies scale with fs.
For example, PB=0.4535*fs(@±0.05dB), SB=0.546*fs(@−54dB).
Note 21. Delay time caused by digital filtering. This time is from setting the 16/20/24bit data of both channels to input
register to the output of analog signal.
Note 22. DAC Æ HPL/HPR/LOUT/ROUT/LAUX/RAUX
