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
20W/ch output power into 4Ω loudspeaker within
10% THD+N and without external heat sink.
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 18.5W/ch output power.
