SYSTEM DESIGN
Figure 12, Figure 13 and Figure 14 show the system connection diagram. Figure 16 , Figure 17 and Figure 18 show the
analog output circuit examples. An evaluation board (AKD4396) is available which demonstrates the optimum layout,
power supply arrangements and measurement results.

Notes:
- Chip Address = “00”. LRCK = fs, BICK = 64fs.
- Power lines of AVDD and DVDD should be distributed separately from the point with low impedance of regulator
etc.
- AVSS 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 load.
- All input pins except pull-down/pull-up pins should not be left floating.
