Note: 7. All digital input pins are held VD or DGND.
(Ta=25°C; VA, VD=4.75 ∼ 5.25V; VT=2.7 ∼ 5.25V; fs=44.1kHz; DEM=OFF)
Note: 8. The passband and stopband frequencies scale with fs.

9. The calculating delay time which occurred by digital filtering. This time is from the input of analog signal to
Normal Operation (PDN=“H”)
Power-down mode (PDN=“L”)
For example, 20.02kHz at -0.02dB is 0.454 x fs. The reference frequency of these responses is 1kHz.
setting the 24bit data of both channels to the output register for ADC.
For DAC, this time is from setting the 24bit data of both channels on input register to the output of analog signal.
