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 I2

C 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
