Product overviewReturn to Top

CXAR41307 is a class F audio power amplifier with a 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 6.5W power under 10% THD + N and 4Ω load and 8.0W power under 3Ω load when boosting to 7.0V. It supports external settings to regulate the BOOST output voltage. The biggest feature of the CXAR41307 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 CXAR41307 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. CXAR41307 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, CXAR41307 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. The CXAR41307 has two versions, namely CXAR41307S, CXAR41307H, unless otherwise specified, the following parameters are based on the actual test values of the CXAR41307S, and the CXAR41307L and CXAR41307S parameters may be slightly different.
