PAM8301
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.
