Description
10V~26V for loudspeaker driver
Loudspeaker output power for 24V
10W x 2CH into 8Ω @0.16% THD+N for stereo
15W x 2CH into 8Ω @0.18% THD+N for stereo
20W x 2CH into 8Ω @0.24% THD+N for stereo
AD82585 is a digital audio amplifier capable of driving
a pair of 8Ω, 20W speaker which operate with play
music at a 24V supply without external heat-sink or fan
requirement.
Sounds processing including:
Volume control (+24dB~-103dB, 0.125dB/step)
Dynamic range control
Power clipping
Channel mixing
User programmed noise gate with hysteresis
Using I2C digital control interface, the user can control
AD82585’s input format selection, mute and volume
control functions. AD82585 has many built-in
protection circuits to safeguard AD82585 from
connection errors.
