CXAR41296 is an audio power amplifier with Class D and Class AB operating modes. In Class D mode, 10W power can be continuously output under VDD = 8.5V, THD + N = 10% and 4Ω load. In class AB mode, under VDD = 8.5V, THD + N = 10% and 4Ω load, 9W power can be continuously output. The CXAR41296 has anti-clipping distortion (ACF) output control function in Class D working mode, 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 signal, significantly improve the sound quality, create comfortable listening enjoyment, and protect the speaker from overload damage. At the same time the chip also has a ACF-Off mode can be configured. The CXAR41296 can realize the free switching function of Class AB and Class D, and can switch to Class AB audio power amplifier mode at any time when troubled by EMI interference of Class D power amplifier. In addition, CXAR41296 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.
