AD82588B-2x20W Stereo/1x 40W Mono Audio Amplifier

AD82588B-2x20W Stereo/1x 40W Mono Digital Audio Amplifier With 20 Bands EQ Functions and 2.1CH Mode DataSheet

Description
    AD82588B is a digital audio amplifier capable of driving a pair of 8Ω, 20W or a single 4Ω, 40W operating at 24V supply. AD82588B is also capable of driving 4Ω, 10W (SE)x2 + 8Ω, 20W (BTL)x1 at 24V supply for 2.1CH application.
    AD82588B can provide advanced audio processing capabilities, such as volume control, 20 bands speaker EQ, 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
    AD82588B from damage due to accidental erroneous operating condition. AD82588B 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. AD82588B is pop free during instantaneous
power switch because of its built-in, robust anti-pop circuit.
