Description
This is a stereo (8Ω)/mono (4Ω) fully digital audio
amplifier with output power which can drive up to
2x10W for stereo or 1x20W for mono at 18V supply
voltage, no external heat-sink or fan is requirement.
Using I2C digital control interface, AD82571A provides
sound processing includes Volume, Bass, Treble, EQ,
Mixing and Dynamic Range Control (DRC). Protection
circuits are provided to protect AD82571A damage
while connection error. It is possible to compose of 2.1
channels with two pieces of AD82571A and 5.1
channels with four pieces.
