General Description
The PAM8302A is a 2.5W 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 PAM8302A is much better
than that of class-AB cousins. It can optimize
battery life thus is ideal for portable applications.
The PAM8302A is available in MSOP-8, SOP-8
and DFN3x3 packages.
