R/W – Read/Write Mode Select
When R/W = 0, a write operation is performed.
When R/W = 1, a read operation is performed.
Default value: 0
MUTx – Soft Mute Control
Where x = 1 through 6, corresponding to the DAC output VOUTx.
These bits are read/write.
Default value: 0
MUTx = 0
Mute disabled (default)
MUTx = 1
Mute enabled
The mute bits, MUT1 through MUT6, are used to enable or disable the soft mute function for the corresponding
DAC outputs, VOUT1 through VOUT6. The soft mute function is incorporated into the digital attenuators. When
mute is disabled (MUTx = 0), the attenuator and DAC operate normally. When mute is enabled by setting
MUTx = 1, the digital attenuator for the corresponding output is decreased from the current setting to the infinite
attenuation setting, one attenuator step (0.5 dB) at a time. This provides a quiet, pop-free muting of the DAC
output. On returning from soft mute, by setting MUTx = 0, the attenuator is increased one step at a time to the
previously programmed attenuation level.

Where x = 1 through 6, corresponding to the DAC output VOUTx.

Default value: 0
DACx = 0
DAC operation enabled (default)
DACx = 1
DAC operation disabled
The DAC operation controls are used to enable and disable the DAC outputs, VOUT1 through VOUT6. When
DACx = 0, the output amplifier input is connected to the DAC output. When DACx = 1, the output amplifier input
is switched to the dc common-mode voltage (VCOM), equal to VCC/2.
