Low THD+N  
Superior Low Noise  
Efficiency up to 90%  
Short Circuit Protection  
Thermal Shutdown  
Few External Components to Save the  
Space and Cost  
Pb-Free Package  
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  
directly, requiring no low-pass output filters,thus  
to save the system cost and PCB area.  
With the same numbers of external components,  
the efficiency of the PAM8403 is much better than  
that of class-AB cousins. It can extend the battery  
life, ideal for portable applications.
