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
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.
The PAM8403 is available in SOP-16 package.
