CXAS42230 is a digital audio amplifier capable of driving 25W (BTL) each to a pair of 8 load speaker and 50W (PBTL) to a 4 load speaker operating at 24V supply without external heat-sink or fan requirement with play music. CXAS42230 provides advanced audio processing functions, such as volume control, 30 EQ bands, audio mixing, 3D surround sound and Dynamic Range Control (DRC)

CXAS42230 is a digital audio amplifier capable of driving 25W (BTL) each to a pair of 8 load speaker and 50W (PBTL) to a 4 load speaker operating at 24V supply without external heat-sink or fan requirement with play music. CXAS42230 provides advanced audio processing functions, such as volume control, 30 EQ bands, audio mixing, 3D surround sound and Dynamic Range Control (DRC). These are fully programmable via a simple I2 C control interface. Robust protection circuits are provided to protect CXAS42230 from damage due to accidental erroneous operating condition. The full digital circuit design of CXAS42230 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. CXAS42230 is pop free during instantaneous power on/off or mute/shut down switching because of its robust built-in anti-pop circuit
