Description
AD82586C is a digital audio amplifier capable of
driving a pair of 8Ω, 20W operating at 24V supply
without external heat-sink or fan requirement with play
music.
AD82586C 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
AD82586C from damage due to accidental erroneous
operating condition. AD82586C 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. AD82586C is pop free during instantaneous
power switch because of its built-in, robust anti-pop
circuit.
