Description

The PAM8301 is a 1.5W Class-D mono audio amplifier. Its low THD+N feature offers high quality sound reproduction. The new filterless architecture allows the device to drive speaker directly instead of using low-pass output filters, therefore saving system cost and PCB area. With the same number of external components, the efficiency of the PAM8301 is much better than that of Class-AB cousins. It can optimize battery life thus is ideal for portable applications. The PAM8301 is available in TSOT26 package.
