Frequency Response
Note 9. The passband and stopband frequencies scale with fs. The reference frequency of these responses is 1kHz.
Note 10. The calculated delay time induced by digital filtering. This time is from the input of an analog signal to the
MS1096-E-01
setting of 24bit data both channels to the ADC output register for ADC.
