Description
This is a stereo (8Ω)/mono (4Ω) fully digital audio amplifier with output power which can drive up to 2x12W for stereo or 1x24W for mono at 24V supply voltage, no external heat-sink or fan is requirement. Using I2C digital control interface, AD82581B provides input format selection, mute and volume control function. Protection circuits are provided to protect AD82581B damage while connection error.
