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 18V supply
voltage, no external heat-sink or fan is requirement.
z Loudspeaker output power for 18V with proper
cooling method
2×14W into 8Ω@1% THD+N for stereo
1×29W into 4Ω@1% THD+N for mono
z Anti-pop design
Using I2C digital control interface, AD82571B provides
input format selection, mute and volume control
function. Protection circuits are provided to protect
AD82571B damage while connection error.
