Note:
Use low ESR (Equivalent Series Resistance) capacitors. When using polarized capacitors, the positive polarity pin
should be connected to the CP and VSS2 pin.
VSS1 and VSS2 should be separated from digital system ground.
Digital input pins should not be allowed to float.
Digital Ground
shows the system connection diagram. An evaluation board (AKD4420) is available for fast evaluation as well
