PAM8403 is a small, dual output, digital amplifier chip. HD quality highlights the advantages of digital chips, circuits use the most reasonable peripheral configuration. Power supply filtering is with SMD LOW ESR Tantalum capacitors
Do not reverse the positive and negative power supply voltage and Do not exceed 5.5V, these two violations would cause IC damage.
Try using shielded input cable, can play a role in immunity, eliminate clutter current sound.
Output stage is Cmos tube, BTL output drive mode. Do not connect the speaker from output to the negative (ground)
Power supply: DC 5V @ least 1A
Power supply range: 2.5-5.5V
Output power: 3W + 3W (3.6 ohms)
Dimensions: 24 * 15 * 3mm; positioning hole size: 20mm aperture spacing: 2 mm
Quality fiber-glass PCB
