DAPSV: DAC Power-Save Control (DAC)

Default value: 1

DAPSV = 0

Normal operation

DAPSV = 1

Power-save mode (default)

The DAPSV bit controls DAC power-save mode. In power-save mode, DAC outputs are forced to Vcom with a

fade-out sequence, the internal DAC data are reset and the DAC goes into the power-down state. For

power-save mode release, a fade-in sequence is applied on the DAC outputs in resume process. The serial

mode control is enabled during this mode. A waiting time of more than 2048/fS is required for the proper status

change by this power-save control on/off. As the default state after power on is the power-save mode and the

DAC outputs are disabled (VCOM), release from the power-save mode is required for normal operation. The

detailed sequence and timing for DAPSV control is shown Figure 22 and Figure 23.

NOTE:

It is recommended that changing/stopping clocks or changing the audio interface

mode be performed in power-down mode in order to avoid unexpected pop/click

noise and performance degradation.

S/E: DAC Output Configuration Control (DAC)

Default value: 0

S/E = 0

Differential (default)

S/E = 1

Single-ended

The S/E bit allows the user to select the configuration of the DAC output on the VOUTX pins according to

application circuit.
