Note 14. The passband and stopband frequencies scale with fs. For example, 21.768kHz at −0.02dB is 0.454 x fs.
Note 15. The calculated delay time induced by digital filtering. This time is from the input of an analog signal
to the setting of 24bit data both channels to the ADC output register for ADC.

Note 16. SMUTE, SEL2-0, CSN/CAD1, CCLK/SCL, CDTI/SDA and I2C pins correspond to 5V tolerant.
Note 17. When AC coupled capacitor is connected to MCLK pin.
Note 18. SMUTE pin is internally connected to a pull-down resistor. (typ. 100kΩ)
