SYSTEM DESIGN
Figure 14and Figure 15 show the system connection diagram. An evaluation board (AKD4340) is available in order to
allow an easy study on the layout of a surround 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 for pull-up pin must not be left floating.
