General Description

The PAM8803 is a 3W, class-D audio amplifier
with 64-step digital volume control. It offers low
THD+N, allowing it to produce high-quality sound
reproduction. The new filterless architecture
allows the device to drive the speaker directly,
without needing low-pass output filters , which will
save 30% system cost and 75% PCB area.

With the same numbers of external components,
the efficiency of the PAM8803 is much better than
class-AB cousins. It can extend the battery life,
ideal for portable applications.
