The Digital-to-Analog converter output will mute when enabled. The quiescent voltage on the output
will be retained. The muting function is affected, similar to attenuation changes, by the Soft and Zero
Cross bits. The MUTEC pin will become active during the mute period if the Mute function is enabled
for both channels in the pair.
Default = 0
The Digital Volume Control registers allow independent control of the signal levels in 1-dB increments
from 0 to -119 dB. Volume settings are decoded as shown in Table 10. The volume changes are im-
plemented as dictated by the Soft Ramp and Zero Cross bits. All volume settings less than -119 dB
are equivalent to enabling the MUTE bit.
Default = 10
00 - Immediate Change
01 - Zero Cross
10 - Soft Ramp
11 - Soft Ramp and Zero Cross
When Immediate Change is selected all level changes will be implemented immediately in one step.
