Output Volume
The AK4356 includes channel independent digital output volumes (ATT) with 256 levels at 0.5dB steps including MUTE.
These volumes are in front of the DAC and can attenuate the input data from 0dB to –127dB and mute. When changing
levels, transitions are executed via soft changes; thus no switching noise occurs during these transitions.
n
De-emphasis filter
A digital de-emphasis filter is available for 32, 44.1 or 48kHz sampling rates (tc=50/15
m
s). It can be set for DAC1
(SDTI1), DAC2 (SDTI2) and DAC3 (SDTI3) independently. It is enabled or disabled with the control register data of
DEM1-0 and DFS1-0. The de-emphasis filter is disabled at double or 4 times sampling mode (except for DFS0 = DFS1 =
“0”).
