产品简介

CXAR41106是一款立体声、高效率的D级音频放大器，采用TQFN5x5-32封装。无滤波器的D类结构消除了外部低通滤波器，节省了PCB空间和BOM成本。CXAR41106还具有扩展时钟功能，可减少高频辐射和降低EMI噪声。当输出（VOUTP和VOUTN）交叉在一起时，过零变化函数改变增益，可以使pop噪声最小。功率限制功能可以在输出信号超过扬声器极限额定值时保护扬声器。无剪辑和DRC功能消除了大输入信号时的失真，可以将高动态输入信号适合于小动态扬声器。工作电压从8V到16.5V。CXAR41106能够在12V下驱动6W进入8W扬声器，并提供热保护和过电流保护。CXAR41106还可以检测到防止扬声器音圈损坏的DC。

The CXAR41106 is a stereo, high efficiency, Class-D audio amplifier available in a TQFN5x5-32 package. The filter-free Class-D architecture eliminates the external low pass filters and saves the PCB space and BOM costs. The CXAR41106 also has spread clock function that reduces the high frequency radiation and low the EMI noise. The Zero-crossing-change function changes the gain when both output (VOUTP and VOUTN) crossing together can minimum the pop noise. The power limit function can protect the speaker when output signal excesses the speaker limit rating. The non-clip and DRC functions eliminate the distortion at large input signal and can fit the high dynamic input signal to a small dynamic speaker. The operating voltage is from 8V to 16.5V. The CXAR41106 is capable of driving 6W at 12V into 8W speaker and provides thermal and over-current protections. The CXAR41106 also can detect the DC that prevents the speaker voice coil being destroyed.
