Description

The AD52050 is a high efficiency stereo class-D

audio amplifier with adjustable power limit function.

The loudspeaker driver operates from 4.5V~14.4V

supply voltage. It can deliver 15W/CH output power

into 4? loudspeaker within 10% THD+N at 12V

supply voltage and without external heat sink when

playing music.

The adjustable power limit function allows user to

set a voltage rail lower than half of 5.5V to limit the

amount of current through the speaker.

Output DC detection prevents speaker damage

from long-time current stress. AD52050 provides

superior EMC performance for filter-free application.

The output short circuit and over temperature

protection include auto-recovery feature.
