DZFM: Data Zero Detect Mode
0: Channel Separated Mode
1: Channel ANDed Mode
If the DZFM bit is set to “1”, the DZF pins of both channels go to “H” only when the input data at both
channels are continuously zeros for 8192 LRCK cycles.

SYSTEM DESIGN
Figure 9 shows the system connection diagram. An evaluation board (AKD4381) is available in order to allow an easy
study on the layout of a surrounding circuit.

Notes:
- LRCK = fs, BICK = 64fs.
- When AOUT drives some capacitive load, some resistor should be added in series between AOUT and capacitive
load.
- All input pins except pull-down/pull-up pins should not be left floating.
