Description
AD82584 is a digital audio amplifier capable of
driving 15W (BTL) each to a pair of 8Ω load speaker
and 30W (PBTL) to a 4Ω load speaker operating at
24V supply without external heat-sink or fan
requirement with play music. AD82584 is also capable
of driving 4Ω, 10W (SE)x2 + 8Ω, 20W (BTL)x1 at 24V
supply for 2.1CH application.
AD82584 can provide advanced audio processing
functions, such as volume control, 20 EQ bands, audio
mixing, 3D surround sound and Dynamic Range
Control (DRC). These are fully programmable via a
simple I2C control interface. Robust protection circuits
are provided to protect AD82584 from damage due to
accidental erroneous operating condition. The full
digital circuit design of AD82584 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. AD82584 is pop free during instantaneous
power on/off or mute/shut down switching because of
its robust built-in anti-pop circuit.
