AD82586C
Description
AD82586C is a digital audio amplifier capable of driving a pair of 8Ω, 20W operating at 24V supply without external heat-sink or fan requirement with play music. AD82586C can provide advanced audio processing capabilities, such as volume control, 20 bands speaker EQ, audio mixing, 3D surround and Dynamic Range Control (DRC).
