General Description:

The AF8403 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, requiring no low-pass output filters, thus to save the and PCB area. With the same numbers of external components, the efficiency of the AF8403 is much better than that of class-AB cousins. The AF8403 is available in a SOP16 package.
