Description

AD82010 is a digital audio amplifier capable of driving

a pair of 8Ω,20W or a single 4Ω,40W speaker, both

which operate with play music at a 24V supply .

Using I2C digital control interface, the user can control

AD82010’s input format selection, mute and volume

control functions. AD82010 has many built-in

protection circuits to safeguard AD82010 from

connection errors.
