● Operating voltage: 2.5V - 5.5V
● Maximum output power: 3W*2(5V 4Ω)
● Board Size: apporx.30*20*16mm
● Built with switch Potentiometer,can adjust the volume and control power switch freely!
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.
