Description
The AD52060 is a high efficiency stereo class-D audio amplifier with adjustable power limit function.
The loudspeaker driver operates from 8V~26Vsupply voltage. It can deliver 20W/CH output power into 8Ω loudspeaker within 1% THD+N at 24V supply voltage and without external heat sink whenplaying music.
AD52060 provides parallel BTL (Mono)application, and it can deliver 40W into 4Ω loudspeaker at 24V 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. AD52060 provides superior EMC performance for filter-free application.
The output short circuit and over temperature protection include auto-recovery feature.
