Description The AD53060 is a high efficiency stereo class-D audio amplifier with adjustable power limit function. The loudspeaker driver operates from 4.5V~20V supply voltage. It can deliver 15W/CHx4 output power into 8 loudspeaker within 1% THD+N at 18V supply voltage and without external heat sink requirement when playing music. AD53060 provides parallel BTL configuration for stereo application also, and it can deliver 25W/CHx2 into 4 loudspeaker at 18V supply voltage. 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. AD53060 provides superior EMC performance for filter-free application. The output short circuit and over temperature protection include auto-recovery feature.
