AD82587D is a digital audio amplifier capable of
driving a pair of 8,20W or a single 4,40W speaker,
both which operate with play music at a 24V supply
without external heat-sink or fan requirement.
20W x 1ch into 4@ 0.17% THD+N
30W x 1ch into 4@ 0.2% THD+N
40W x 1ch into 4@ 0.24% THD+N
z Sounds processing including:
Volume control (+24dB~-103dB, 0.125dB/step)
Dynamic range control
Using I2C digital control interface, the user can control
AD82587D’s input format selection, mute and volume
control functions. AD82587D has many built-in
protection circuits to safeguard AD82587D from
connection errors.
Power clipping
Channel mixing
User programmed noise gate with hysteresis window
DC-blocking high-pass filter
