3.6V; DVDD=1.6
3.6V; fs=44.1kHz)
Parameter
ADC Digital Filter (Decimation LPF):
Passband (
Note 15
)
Stopband (
Note 15
)
Passband Ripple
Stopband Attenuation
Group Delay (
Note 16
)
Group Delay Distortion
ADC Digital Filter (HPF):
HPF1-0 bits = “00”
Frequency Response (
Note 15
)
Note 15. The passband and stopband frequencies scale with fs (system sampling rate).
For example, PB=0.454*fs (@
1.0dB). Each response refers to that of 1kHz.
Note 16. The calculated delay time caused by digital filtering. This time is from the input of analog signal to setting of the
16-bit data of both channels from the input register to the output register of the ADC. This time includes the
group delay of the HPF.
