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.

With the same numbers of external components,

the efficiency of the PAM8403 is much better than

that of class-AB cousins.

The PAM8403 is available in SOP-16 package.
