CXAR41305 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 5.5W power under 10% THD + N and 4Ω load when boosted to 6.5V. When boosted to 7V and 3Ω load, 7.0W power can be continuously output. It supports external settings to regulate the BOOST output voltage. The biggest feature of the CXAR41305 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 CXAR41305 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. CXAR41305 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 CXAR41305 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
