Setting the MUTEALL register bit will apply a 'soft' mute to the input of all the DAC digital filters:

Soft Mute Select:
0 : Normal operation
1: Soft mute all channels
Refer to Figure 19 for the plot of application and release of soft mute.
Note that all other means of muting the DAC channels: setting the PL[3:0] bits to 0, setting the
PDWN bit or setting attenuation to 0 will cause much more abrupt muting of the output.
ADC MUTE MODES
Each ADC channel also has a mute control bit, which mutes the inputs to the ADC.
