Note 22. The passband and stopband frequencies scale with fs (system sampling rate).
For example, ADC is PB=0.454*fs (@-1.0dB). Each response refers to that of 1kHz.
Note 23. The calculated delay time caused by digital filtering. This time is from the input of analog signal to setting of the
16-bit data of both channels from the input register to the output register of the ADC. This time includes the
group delay of the HPF. For the DAC, this time is from setting the 16-bit data of both channels from the input
register to the output of analog signal. Group delay of DAC part is 22/fs(typ) at PMADL=PMADR bits = “0”.
Note 24. When PMADL bit = “1” or PMADR bit = “1”, the HPF of ADC is enabled but the HPF of DAC is disabled.
When PMADL=PMADR bits = “0”, PMDAC bit = “1”, the HPF of DAC is enabled but the HPF of ADC is
disabled.
Note 25. These frequency responses scale with fs. If a high-level and low frequency signal is input, the analog output clips
to the full-scale.
