PAM8003

FILTERLESS 2.5W CLASS-D STEREO AUDIO AMPLIFIER

Description

The PAM8003 is a 2.5W, 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 saving the system

cost and PCB area.

With the same numbers of external components, the efficiency of the

PAM8003 is much better than that of class-AB cousins. It can extend

the battery life, making it ideal for portable applications.

The PAM8003 is available in SO-16 package.
