FILTERLESS CLASS-D MONO AUDIO AMPLIFIER

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.
