De-emphasis Filter
The AK4371 includes a digital de-emphasis filter (tc = 50/15
μ
s), using an IIR filter corresponding to three sampling
frequencies (32kHz, 44.1kHz and 48kHz). The de-emphasis filter is enabled by setting DEM1-0 bits (Table 19).

Bass Boost Function
By controlling the BST1-0 bits, a low frequency boost signal can be output from DAC. The setting value is common for
both channels (Table 20).

System Reset
PDN pin should be held to “L” upon power-up. The AK4371 should be reset by bringing PDN pin “L” for 150ns or more.
All of the internal register values are initialized by the system reset. After exiting reset, VCOM, DAC, HPL, HPR, LOUT,
ROUT and MOUT switch to the power-down state. The contents of the control register are maintained until the reset is
completed.
The DAC exits reset and power down states by MCKI after the PMDAC bit is changed to “1”. The DAC is in power-down
mode until MCKI is input.
