AD82587D is a digital audio amplifier capable of driving a pair of 8?,20W or a single 4?,40W speaker, both which operate with play music at a 24V supply without external heat-sink or fan requirement.

Using IC digital control interface, the user can control AD82587D’s input format selection, mute and volume control functions. AD82587D has many built-in protection circuits to safeguard AD82587D from connection errors.
