PAM8403H EVB User Guide 9. PCB Layout Guidelines Grounding
(1) Use plane grounding or separate grounds (2) Do not use one line connecting power GND and analog GND (3) Output noise grounds must tie to system ground at the power in exclusively. (4) Signal currents for the inputs need to be returned to quite ground. This ground only ties to the signal components and the GND pin.
Power Supply Others
(1) The power supply capacitors (C2, C3, C9, C1, C10) need to place very close to the PAM8003’s pins. (2) Input capacitors (C5, C7) place closed to input pin as near as possible
