FILTERLESS 2.5W CLASS-D STEREO AUDIO AMPLIFIER
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.
