PAM8403DR-H

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.

Features：

3W Output at 10% THD with a 4Ω Load and 5V Power Supply
Filterless, Low Quiescent Current and Low EMI
Low THD+N
Superior Low Noise
Efficiency up to 90%
Short Circuit Protection
Thermal Shutdown
Few External Components to Save the Space and Cost
