Description
AD83586 is a digital audio amplifier capable of
driving a pair of 8Ω, 15W plus a single 4Ω, 30W, or a
pair of 4Ω, 25W or a single 4Ω, 50W speaker
operating at 24V supply with proper cooling method.
AD83586 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
AD83586 from damage due to accidental erroneous
operating condition. AD83586 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. AD83586 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 AD83586 to realize
5.1 channels for home theater applications.
