PAM8803

3W Filterless Stereo Class-D Audio Amplifier

with Digital Volume Control

Key Features

General Description

3W Output at 10% THD with a 4Ω Load and

5V Power Supply

Filterless, Low Quiescent Current and Low

EMI

Low THD+N

64-step Digital Volume Control

Superior Low Noise

Low pop noise

Efficiency up to 90%

Short Circuit Protection

Thermal Shutdown

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.
