Note 27. The passband and stopband frequencies scale with fs (system sampling rate).
For example, PB=0.454*fs (@−0.7dB). Each response refers to that of 1kHz.
Note 28. The calculated delay time caused by digital filtering. This time is from setting the 16-bit data of both channels
from the input register to the output of analog signal.
Note 29. These frequency responses scale with fs. If a high-level and low frequency signal is input, the analog output clips
to the full-scale.
