Description
    AD83586B is a digital audio amplifier capable of
driving a pair of 8Ω, 20W plus a single 4Ω, 40W, or a
pair of 4Ω, 40W or a single 4Ω, 60W speaker
operating at 24V supply with proper cooling method.
AD83586B can provide advanced audio processing
capabilities, such as volume control, 20 bands speaker
EQ, audio mixing, 3D surround and Dynamic Range
Control (DRC). These functions are fully
programmable via a simple I2C control interface.
Robust protection circuits are provided to protect
    AD83586B from damage due to accidental erroneous
operating condition. AD83586B is more tolerant to
noise and PVT (Process, Voltage, and Temperature)
variation than the analog Class-AB or Class-D audio
amplifier counterpart implemented by analog circuit
design. AD83586B is pop free during instantaneous
power switch because of its built-in, robust anti-pop
circuit.
    The output stage is flexibly configurable for 2.1
channel, stereo or mono applications. Furthermore, it
is possible to use three pieces of AD83586B to realize
5.1 channels for home theater applications.
