Description

AD83586C is a digital audio amplifier capable of

driving a pair of 8Ω, 25W (30W peak) plus a single 4Ω,

50W (60W peak), or a pair of 4Ω, 50W (60W peak) or

a single 2Ω, 100W (120W peak) speaker operating at

24V supply with proper cooling method.

AD83586C can provide advanced audio processing

capabilities, such as volume control, 36 bands

speaker EQ, audio mixing, 3D surround and Dynamic

Range Control (DRC). These functions are fully

programmable via a simple I

2C control interface.

Robust protection circuits are provided to protect

AD83586C from damage due to accidental erroneous

operating condition. AD83586C 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. AD83586C is pop free during instantaneous

power switch because of its built-in, robust anti-pop

circuit.
