SYSTEM DESIGN
Figure 9 and 10 show the system connection diagram. An evaluation board (AKD4394) is available which demonstrates
the optimum layout, power supply arrangements and measurement results.

Figure 9. Typical Connection Diagram (Serial mode)
Notes:
- LRCK = fs, BICK = 64fs.
- Power lines of AVDD and DVDD should be distributed separately from the point with low impedance of
regulator etc.
- 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
load.
- All input pins except pull-down/pull-up pins should not be left floating.
