Figure 9 and 10 show the system connection diagram. The output filter circuits are shown in Figure 12 and Figure 13. An
evaluation board (AKD4395) is available which demonstrates the optimum layout, power supply arrangements and
measurement results.

Notes:
Reset & Power down
24bit Audio Data
- LRCK = fs, BICK = 64fs.
- Power lines of AVDD and DVDD should be distributed separately from the point with low impedance of
- AVSS, BVSS and DVSS must be connected to the same analog ground plane.
- When AOUT drives some capacitive load, some resistor should be added in series between AOUT and capacitive
- All input pins except pull-down/pull-up pins should not be left floating.
