AD52582A - 18W Stereo Class-D Audio Amplifier

General Description

The AD52582A is a high efficiency stereo class-D audio amplifier.

The loudspeaker driver operates from 12~24V supply voltage and analog circuit operates at 3.3V supply voltage.

It can deliver 20W/ch output power into 4Ω loudspeaker within 10% THD+N and without external heat sink.
