Description

The PAM8620 is a 20W (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 an 8V to 26V supply at much higher efficiency.

The PAM8620 only requires very few external components, significantly saving cost and board space.

The PAM8620 is available in a small W-QFN5050-32 (Standard) package.
