Note 6. BOOST = “L”.
Note 7. The passband and stopband frequencies scale with fs.
For example, PB=0.4535*fs(@
±
0.05dB), SB=0.546*fs(@-54dB).
Note 8. The calculating delay time which occurred by digital filtering. This time is from setting the 20bit data of both
channels to input register to the output of analog signal.
Note 9. When BOOST pin is “H”, if full scale signal inputs, AK4360 clips at low frequency.
