CXAR41306 is a class-D audio power amplifier with a built-in BOOST boost module. The built-in BOOST boost module can adjust the boost value through an external resistor. Even if it is powered by a lithium battery, it can continuously output 11W power under the condition of boosting to 7.5V and 2Ω load. It supports external settings to regulate the BOOST output voltage. The biggest feature of the CXAR41306 is the anti-clipping distortion (ACF) output control function, which can detect and suppress the clipping distortion (sound breaking) of the output signal caused by the excessive amplitude of the input music and voice signals, and can also adaptively prevent the output clipping caused by the drop in BOOST boost voltage, significantly improve the sound quality, create very comfortable listening enjoyment, and protect the speaker from overload damage. At the same time the chip has a ACF-Off mode. The CXAR41306 has the free switching function of Class AB and Class D, and can switch to Class AB audio power amplifier mode at any time when disturbed by EMI interference of Class D power amplifier. CXAR41306 integrated filter-free digital modulation technology, it can directly drive the speaker, and minimize the distortion and noise of the pulse output signal. The output does not require a filter network, and minimal external components save system space and cost, making it ideal for portable applications. In addition, the CXAR41306 built-in shutdown function to minimize the standby current, but also integrated output over-current protection, on-chip over-temperature protection and power supply under-voltage abnormal protection and other functions
