NOT RECOMMENDED FOR NEW DESIGN
USE PAM8406 PAM8403 FILTERLESS 3W CLASS-D STEREO AUDIO AMPLIFIER Description Pin Assignments 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 saving 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, which makes it well-suited for portable applications.
The PAM8403 is available in SOP-16 package. Features
