PAM8003DR

PAM8003DR is a 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 number 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. Applications include LCD monitors / TVs, notebook computers, portable speakers, portable DVD players, and game machines.
