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.
