Description
AD82589 is an integrated audio system solution,
embedding digital audio processing power stage
amplifier.
AD82589 has a programmable slew-rate
controlled output buffer, which drives one (mono) or
two (stereo) speakers directly. In addition, it is
insusceptible to supply voltage fluctuation due to the
close-loop design.
AD82589 can provide advanced audio processing
capabilities, such as volume control, 24 bands EQ,
audio mixing and Dynamic Range Control (DRC).
These functions are fully programmable via a simple
I2C interface.
Robust protection circuits are provided to protect
AD82589 from damage due to accidental erroneous
operation. AD82589, being a digital circuit design, 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. Furthermore, AD82589 is pop
free during instantaneous power switching because of
its built-in, robust anti-pop circuit.
Applications
z TV audio
z Boom-box, CD and DVD receiver, docking system
z Powered speaker
z Wireless audio
