Frequency Response (Note 7)
Note 7. The passband and stopband frequencies scale with fs. The reference frequency of these responses is 1kHz.
Note 8. The calculated delay time induced by digital filtering. This time is from the input of an analog signal to the
MS0200-E-02
setting of 24bit data both channels to the ADC output register for ADC.
