SYSTEM DESIGN
Figure 23 shows the system connection diagram. An evaluation board (AKD4563A) is available which demonstrates
application circuits, the optimum layout, power supply arrangements and measurement results.

Figure 23. System Connection Diagram
Note:
- AGND and DGND of AK4563A should be distributed separately from the ground of external controller
etc.
- When LOUT/ROUT drives some capacitive load, some resistor should be added in series between
LOUT/ROUT and capacitive load.
