Digital High Pass Filter
The ADC of AK4520A has a digital high pass filter for DC offset cancel. The cut-off frequency of the HPF is
0.9Hz at fs=44.1kHz and also scales with sampling rate(fs).
De-emphasis filter
The DAC of AK4520A includes the digital de-emphasis filter(tc=50/15us) by IIR filter. This filter corresponds to
three frequencies (32kHz,44.1kHz,48kHz). The de-emphasis filter selected by DEM0 and DEM1 is enabled for
input audio data. The de-emphasis is also disabled at DEM0="1" and DEM1="0".
