General 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 save 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 SOT23-6 package.
