AD52050C-26QG28NRR
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 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. AD52050 provides superior EMC performance for filter-free application. The output short circuit and over temperature protection include auto-recovery feature.
