De-emphasis Filter
The AK4650 includes the digital de-emphasis filter (tc = 50/15
μ
s) by IIR filter. Setting the DEM1-0 bits enables the
de-emphasis filter (Table 23).

Bass Boost Function
The BST1-0 bits control the amount of low frequency boost applied to the DAC output signal (Table 24). If the BST1-0
bits are set to “10” (MID Level), AC-coupling capacitor can be sized down to 47
μ
F. If the boosted signal exceeds the full
scale, the analog output clips to the full scale. Figure 20 shows the boost frequency response at –20dB signal input.
