Note 14. The passband and stopband frequencies scale with fs (system sampling rate).
For example, PB=0.454*fs (@−1.0dB). Each response refers to that of 1kHz.
Note 15. The calculated delay time caused by digital filtering. This time is from the input of analog signal to setting of the
16-bit data from the input register to the output register of the ADC. This time includes the group delay of the
HPF.
