SEMIPICK - AD52090 Datasheet / The AD52090 is a high efficiency stereo class-D audio amplifier with adjustable power limit function.The loudspeaker driver operates from 4.5V~26V supply voltage and analog circuit operates at 5V supplyvoltage. It can deliver 30W/CH output power into 4or 8loudspeakerwithin 1% THD+N at 24V supply voltage. AD52090 provides parallel BTL (Mono) application, and it can deliver 60W into 4 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.AD52090output short circuit and over temperature protection include auto-recovery feature.
