Power-down & Reset
The ADC and DAC of AK4551 are placed in the power-down mode by bringing each power down pin, PWAD ,
PWDA = “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 2 shows the power-up sequence when the ADC is powered up before the DAC power-up.
