De-emphasis Filter
The AK4367 includes a digital de-emphasis filter (tc = 50/15
μ
s) by IIR filter corresponding to three sampling frequencies
(32kHz, 44.1kHz and 48kHz). The de-emphasis filter is enabled by setting DEM1-0 bits (Table 7).

Bass Boost Function
By controlling BST1-0 bits, the low frequency boost signal can be output from DAC. The setting value is common in Lch
and Rch (Table 8).

System Reset
The AK4367 should be reset once by bringing PDN pin “L” upon power-up. After exiting reset, VCOM, DAC, HPL,
HPR and MOUT switch to the power-down state. The contents of the control register are maintained until the reset is
done.
DAC exits reset and power down state by MCLK after PMDAC bit is changed to “1”, and then DAC is powered up and
the internal timing starts clocking by LRCK “
↑
”. DAC is in power-down mode until MCLK and LRCK are input.
