Normal Operation Mode
To use the DAC or change analog switches, set the AUTO bit, DAPD bit, MUTE bit and STBY bit to “0”. The DAC is in
power-down mode until MCLK and LRCK are input. The AK4705 is in power-down mode until MCLK and LRCK are
input. Figure 2 shows an example of the system timing at the power-down and power-up by PDN pin.
