DAPSV: DAC Power-Save Control (DAC)
Default value: 1
DAPSV = 0
DAPSV = 1
Normal operation
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/f
S
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 (V
), 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
S/E = 1
Differential (default)
Single-ended
The S/E bit allows the user to select the configuration of the DAC output on the V
OUT
X pins according to
application circuit.
