Each DAC channel (V
OUT
L and V
OUT
R) has a digital attenuator function. The attenuation level may be set from 0
dB to –100 dB in 0.5-dB steps, and also may be set to infinite attenuation (mute). The attenuation level change
from current value to target value is performed by incrementing or decrementing one 0.5-dB step for every 8/f
S
time interval. While the attenuation level change sequence is in progress, new commands for attenuation level
change are not processed, but the new command overwrites the previous command in the command buffer. The
last command for attenuation level change is performed after the present attenuation level change sequence is
finished.
The attenuation level for each channel can be set individually using the following formula, and the foregoing
table shows attenuation levels for various settings:
Attenuation level (dB) = 0.5
