     CXAR41183是一款针对便携式通讯设备设计的音频功率放大器。在电源电压5V时，CXAR41183能在负载为8Ω的扬声器上连续输出1.0 W的功率，同时失真度(THD+N)控制在1%以下，而在3V电源电压及8Ω负载下，它则能输出350mW的功率。CXAR41183仅需要很少外围器件就能提供高质量的音频，其功耗极小。当将SHUTDOWN pin脚位变成低电位时，芯片将进入低功耗关闭模式。CXAR41183 包含的pop以及click噪音抑制电路，可在芯片打开或关闭之时来抑制pop以及click噪音。为了实现最大的灵活性， CXAR41183提供外部增益设定，以及外部控制芯片打开和关闭时间（利用BYPASS CAP.)。CXAR41183采用MSOP-8，3 mm x 3mm DFN封装。The CXAR41183 is an audio power amplifier designed for portable communication device applications such as mobile phone applications. The CXAR41183 is capable of delivering 1.0W of continuous average power to an 8Ω BTL and with less than 1% distortion (THD+N) from a 5.0V power supply, and 350mW to a 8Ω BTL load from a 3V power supply. The CXAR41183 provides high quality audio while requiring few external components and minimal power consumption. It features a low-power shutdown mode, which is achieved by driving the pin with logic low. The CXAR41183 contains circuitry to prevent from ”pop and click” noise that would otherwise occur during turn-on and turn-off transitions. For maximum flexibility, the CXAR41183 provides an externally controlled gain (with resistors), as well as an externally controlled turn-on and turn-off times (with the bypass capacitor). The CXAR41183 is available in a MSOP-8 , 3mm×3mm DFN package.
