AD82588 can provide advanced audio processing capabilities, such as volume control, 18 bands speaker eq, audio mixing, 3d surround and dynamic range control (drc). these functions are fully programmable via a simple i 2 c control interface. robust protection circuits are provided to protect AD82588 from damage due to accidental erroneous operating condition. AD82588 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. AD82588 is pop free during instantaneous power switch because of its built-in, robust anti-pop circuit. the output stage is flexibly configurable for stereo channel or mono applications.
