Default Value: 0
DACx = 0
DACx = 1
DAC Operation Enabled (default)
DAC Operation Disabled
The DAC operation controls are used to enable and disable the DAC outputs, V
OUT
L and V
OUT
R. When
DACx = 0, the corresponding output will generate the audio waveform dictated by the data present on the
DATA pin. When DACx = 1, the corresponding output will be set to the bipolar zero level, or

Digital De-Emphasis Function Control
Default Value: 0
DM12 = 0
DM12 = 1
De-Emphasis Disabled (default)
De-Emphasis Enabled
The DM12 bit is used to enable or disable the Digital De-Emphasis function. Refer to the Typical Performance
Curves of this data sheet for more information.
