The IS31AP2112 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 supply voltage. It can deliver 20W/CH output power into 8Ω loudspeaker within 1% THD+N at 24V supply voltage and without external heat sink when playing music. IS31AP2112 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. IS31AP2112 provides the spread spectrum function to improve EMI performance. The output short circuit and over temperature protection include auto-recovery feature. APPLICATIONS , , , , Monitors , Consumer audio equipment.
