AD83586C- 2x60W Stereo / 1x120W Mono / 2x30W+1x60W 2.1CH
Digital Audio Amplifier with 36 bands EQ and DRC Functions  DataSheet
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 I2C 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.
The output stage is flexibly configurable for 2.1
channel, stereo or mono applications. Furthermore, it
is possible to use two pieces of AD83586C to realize
5.1 channels for home theater applications.
