(Ta=25 C; VA=VD=2.6 3.3V; fs=48kHz; De-emphasis = OFF)
ADC Digital Filter (LPF):
Passband (Note 31)
Stopband (Note 31)
Passband Ripple
Stopband Attenuation
Group Delay (Note 32)
Group Delay Distortion
ADC Digital Filter (HPF):
Frequency Response (Note 31)
DAC Digital Filter:
Passband (Note 31)
Stopband (Note 31)
Passband Ripple
Stopband Attenuation
Group Delay (Note 32)
DAC Digital Filter + Analog Filter:
Frequency Response
Note 31. The passband and stopband frequencies scale with fs (system sampling rate).
Note 32. The calculating delay time which occured by digital filtering, This time is from the input of analog signal to
MS0028-E-00
For example, ADC is PB=0.454*fs (@-1.0dB), DAC is PB=0.454*fs (@-0.1dB).
setting the 16 bit data of both channels on input register to the output register of ADC. And this time include
group delay of HPF. For DAC, this time is from setting the 16 bit data of both channels on input register to the
output of analog signal.
