产品简介

CXAR41113是一个单片集成电路，它提供精确的直流音量控制，以及一个立体声D类音频功率放大器，能够以低于10%的THD+N将9W输出到8W（12V）。CXAR41113的音量控制衰减器范围为36分贝（VVOLUME=5V）到-40分贝（VVOLUME=0V），32步。内部增益设置的优点是可以减少元件和PCB面积。热保护和过流保护的电路集成在CXAR41113中。它保护芯片不受过温和过流故障的破坏。为了简化音频系统的设计，CXAR41113将外部耳机驱动器的线路输出与音量控制和外部耳机驱动器的5V调节器结合在一起，如应用电路中所示，通过连接到CXAR41113模式管脚的耳机插孔的开关管脚可以关闭扬声器输出
·D级高效运行。
·带滞后的32步直流音量控制
·每通道输出功率9W，12V负载8W，D级输出
·12V时每个通道输出12W到6W负载，D级输出·5V LDO输出，用于为CXAR41115耳机驱动程序供电
·带直流音量控制的CXAR41115耳机驱动程序的线路输出·关机模式下的低电流消耗（典型为10mA）
·过电流保护后热保护和过电流保护将自动恢复

The CXAR41113 is a monolithic integrated circuit, which provides precise DC volume control, and a stereo Class-D audio power amplifiers capable of producing 9W into 8W (12V) with less than 10% THD+N. The attenuator range of the volume control in the CXAR41113 is from 36dB (VVOLUME =5V) to -40dB (VVOLUME =0V) with 32 steps. The advantage of internal gain setting can be less components and PCB area. The circuitries of both thermal and the over-current protections are integrated in the CXAR41113. It protects the chip from being destroyed by over temperature and over current failure. To simplify the audio system design, the CXAR41113 combines a line output for external headphone driver with volume control and a 5V regulator for external headphone drive, where the speaker output can be switched off by the headphone jack’s switch pin that connects to the CXAR41113’s mode pin as shown in the application circuit
