SHARP ROLL-OFF FILTER CHARACTERISTICS
(Ta = 25

Parameter
Digital filter
Passband

0.05dB (Note 9)
-6.0dB
Stopband (Note 10)
Passband Ripple
Stopband Attenuation
Group Delay (Note 11)
Digital Filter + SCF
Frequency Response
80.0kHz
Fs=192kHz
Notes: 10. The passband and stopband frequencies scale with fs(system sampling rate).
For example, PB=0.4535×fs (@
±
0.05dB), SB=0.546×fs.
11. The calculating delay time which occurred by digital filtering. This time is from setting the 16/24bit data
of both channels to input register to the output of analog signal.
