AD82585-2X20W Stereo Digital Audio Amplifier


AD82585-2X20W Stereo Digital Audio Amplifier with DRC DataSheet

Description
    AD82585 is a digital audio amplifier capable of driving a pair of 8Ω, 20W speaker which operate with play music at a 24V supply without external heat-sink or fan
requirement. Using I2C digital control interface, the user can control AD82585’s input format selection, mute and volume control functions. AD82585 has many built-in protection circuits to safeguard AD82585 from connection errors.
