Note: 14. The passband and stopband frequencies scale with fs.
For example, PB = 0.4535×fs (@±0.01dB), SB = 0.546×fs.
15. The calculating delay time which occurred by digital filtering. This time is from setting the 16/20/24bit data of
both channels to input register to the output of analog signal.
FILTER CHARACTERISTICS (fs = 96kHz)
(Ta = 25°C; AVDD = 4.75~5.25V; DVDD = 3.0~5.25V; fs = 96kHz; Double Speed Mode; DEM = OFF)
