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.
z Loudspeaker output power for 24V with proper
Using I2C digital control interface, AD82581B provides
cooling method
input format selection, mute and volume control
2×26W into 8Ω@1% THD+N for stereo
function. Protection circuits are provided to protect
1×53W into 4Ω@1% THD+N for mono
AD82581B damage while connection error.
z Anti-pop design
