MUTDA[8:1] DAC Soft Mute control
These bits are used to enable or disable the Soft Mute function for the corresponding DAC
outputs, VOUT. The Soft Mute function is incorporated into the digital attenuators.
When Mute is disabled (MUTDA[8:1] = 0), the attenuator and DAC operate normally. When Mute
is enabled by setting MUTDA[8:1] = 1, the digital attenuator for the corresponding output
decreases from the current setting to infinite attenuation with an s-curve response and time set
by ATSPDA.
By setting MUTDA[8:1] = 0, the attenuator increases to the last attenuation level with s-curve
response in the same manner as it is for decreasing levels. This configuration provides pop and
zipper noise-free muting of the DAC output.
The Soft Mute control uses the same digital attenuation level resource setting as the DAC. Mute
control has priority over the digital attenuation level setting.
Default value: 0000 0000.
