AD82571 - Elite Semiconductor

AD82571 2 x 10W Stereo / 1 x 20W Mono Digital Audio Amplifier

AD82571 is a digital audio amplifier capable of driving a pair of 8Ω,10W or a single 4Ω,20W speaker, both which operate at a 18V supply without external heat-sink or fan requirement. Using I2C digital control interface, the user can control AD82571’s input format selection, mute and volume control functions. AD82571 has many built-in protection circuits to s.
