CXAR41292 is an anti-clipping, binaural filter-free Class-D audio power amplifier. Under the conditions of VDD = 8.5V, THD + N = 10% and 4Ω load, it can continuously output 2 × 9.5W power. The CXAR41292 has anti-clipping distortion (ACF) output control function, which can detect and suppress the clipping distortion (broken sound) of the output signal caused by the input music and voice signal amplitude, 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. CXAR41292 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 CXAR41292 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.
