Power-down & Reset
The ADC and DAC of AK4555 are placed in the power-down mode by bringing each power down pin, PWADN,
PWDAN = “L” independently and each digital filter is also reset at the same time. These resets should always be done
after power-up. In case of the ADC, an anlog initialization cycle starts after exiting the power-down mode. Therefore, the
output data, SDTO becomes available after 2081 cycles of LRCK clock. This initialization cycle does not affect the DAC
operation. Figure 5 shows the power-up sequence when the ADC is powered up before the DAC power-up.
