Power Down & Reset
The ADC and DAC of AK4528 are placed in the power-down mode by bringing a power down pin(PDN)=“L” and each
digital filter is also reset at the same time. The internal register values are initialized by PDN=“L”. This reset should always
be done after power-up.
In case of serial mode, the default value of both control registers for ADC and DAC are in reset state (RSTADN=
RSTDAN = ”0” ), each register sholud be cancelled after doing the needed setting. In case of the ADC, an analog
initialization cycle starts after exiting the power-down or reset state. Therefore, the output data, SDTO becomes available
after 516 cycles of LRCK. In case of DAC, the initialization cycle starts after PDN= “H” or PWVR bit = “1”. The power
down mode can be also controlled by the registers (PWAD, PWDA).
