General Description
The PAM8403 is a 3W, class-D audio amplifier. It offers low THD+N, allowing it to achieve high quality sound reproduction. The new filterless architecture allows the device to drive the speaker
, requiring no low-pass output filters,thus to save the and PCB area.

KEY FEATUREs
3W Output at 10% THD with a 4Ω Load and 5V Power Supply
Filterless, Low Quiescent Current and Low EMI
Low THD+N
Superior Low Noise
Efficiency up to 90%
Short Circuit Protection
Thermal Shutdown
Few External Components to Save the
Space and Cost
