Description
    The AD52582A is a high efficiency stereo class-D audio amplifier. The loudspeaker driver operates from 12~24V supply voltage and analog circuit operates at 3.3V supply voltage. It can deliver 18W/ch output power into 4Ω loudspeaker within 10% THD+N.
    The gain of the amplifier is controlled by two gain select pins. The gain selections are 20, 26, 32, 36 dB.
    The AD52582A packaged as E-TSSOP 24L is a stereo audio amplifier with high efficiency and low thermal resistance which leads to no external heat sink requirement under 18W/ch output power with play music.
