Figure 5. Typical Connection Diagram
Notes:
- When AOUT drives some capacitive load, some resistor should be added in series between AOUT and capacitive load.
- ALL input pins except internal pull-down pins should not be left floating.
- Decoupling capacitor, especially 0.1μF ceramic capacitor for high frequency should be placed as near to VDD and
VREF pins as possible.
- System ground including DSP/μP should be separated from AK4351’s VSS. Both grounds should be connected by one
point at power supply or regulator on system board.
