z Wireless audio
128x~512x Fs for 64kHz / 88.2kHz / 96kHz
z USB speaker
64x~256x Fs for 128kHz/176.4kHz/192kHz
z Supply voltage
Description
3.3V for digital circuit
12V~18V for loudspeaker driver
z Loudspeaker output power for 18V
10W x 2CH into 8Ω @0.35% THD+N for stereo
20W x 1CH into 4Ω @0.32% THD+N for mono
AD82571 is a digital audio amplifier capable of driving
a pair of 8Ω,10W or a single 4Ω,20W speaker, both
which operate at a 18V supply without external
heat-sink or fan requirement.
z Anti-pop design
z Over-temperature protection
z Internal PLL
z Under-voltage shutdown
z Over-current protection
z I2C control interface
Using I2C digital control interface, the user can control
AD82571’s input format selection, mute and volume
control functions. AD82571 has many built-in
protection circuits to safeguard AD82571 from
connection errors.
