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
