Description
AD82586 is a digital audio amplifier capable of
driving a pair of 8Ω, 10W or a single 4Ω, 20W speaker
operating at 24V supply without external heat-sink or
fan requirement. It’s also capable of driving a pair of
8Ω, 15W or a single 4Ω, 30W speaker operating at a
24V supply with proper cooling method.
AD82586 can provide advanced audio processing
capabilities, such as volume control, 8 EQ bands,
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 AD82586 from damage
due to accidental erroneous operating condition.
AD82586 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. AD82586 is pop
free during instantaneous power switch because of its
built-in, robust anti-pop circuit.
The output stage is flexibly configurable for stereo or
mono applications. In addition, AD82586 provides a
sub-woofer PWM output port for the increasingly
popular 2.1 channel applications. The programmable
audio bass content of this subwoofer PWM output port
can drive an external, low cost digital amplifier power
stage (such as ESMT’s AD9256H, AD92580, ..).
Furthermore, it is possible to use three pieces of
AD82586 to realize 5.1 channels for home theater
applications.
