Applications
The PAM8620 is a 15W (per channel) stereo
class-D audio amplifier which offers low THD+N
(0.2%), low EMI, and good PSRR thus high-
quality sound reproduction.
The PAM8620 runs off of a 8V to 26V supply at
much higher efficiency than competitors’ Ics.
The PAM8620 only requires very few external
components, significantly saving cost and board
space.
The PAM8620 is available in a QFN5x5-32L
package.
n Flat monitor /LCD TVS
n Multi-media speaker System
n DVD players, game machines
n Boom Box
n Music instruments
