2.5W FILTERLESS CLASS-D MONO AUDIO AMPLIFIER
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 speakers 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
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, DFN3x3-8 and
DFN2x2-8 packages.
