AD52058C-2x15WStereo Class-D Audio Amplifier with Power Limit  DataSheet
Description
The AD52058C 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 4W 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 5V to limit the
amount of current through the speaker.
Output DC detection prevents speaker damage
from long-time current stress.AD52058C provides
superior EMC performance for filter-free application.
The output short circuit and over temperature
protection include auto-recovery feature.
