FILTERLESS 2.5W CLASS-D STEREO AUDIO AMPLIFIER
Description
The PAM8003 is a 2.5W, 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 saving system cost 
and PCB area. 
 
With the same numbers of external components, the efficiency of the 
PAM8003 is much better than that of class-AB cousins. It can extend 
the battery life, ideal for portable applications. 
 
The PAM8003 is available in SOP-16L package
