XA8323 is an integrated audio system solution, embedding digital audio processing power stage amplifier.
XA8323 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.
XA8323 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 XA8323 from damage due to accidental erroneous operation. XA8323, 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, XA8323 is pop free during instantaneous power switching because of its built-in, robust anti-pop circuit.
