ASAHI KASEI
(Ta=25°C; AVDD=2.4 ∼ 3.6V; DVDD=1.6 ∼ 3.6V; fs=44.1kHz)
Parameter
ADC Digital Filter (Decimation LPF):
Passband (Note 14)
Stopband (Note 14)
Passband Ripple
Stopband Attenuation
Group Delay (Note 15)
Group Delay Distortion
ADC Digital Filter (HPF): HPF1-0 bits = “00”
Frequency Response (Note 14)
Note 14. The passband and stopband frequencies scale with fs (system sampling rate).
Note 15. The calculated delay time caused by digital filtering. This time is from the input of analog signal to setting of the
