CXAR41274是一个8针SOP-8、MSOP-8、SOP-8（FD）或TDFN3X3-8的单声道音频功率放大器，带有热垫组件。在5V电源电压下，驱动2W连续均方根功率以桥连负载（BTL）方式进入4Ω负载。在上述操作条件下，其THD小于1%。对于低电流消耗应用程序，支持SHDN模式以在CXAR41274空闲时禁用它。电流消耗可以进一步降低到1μA以下。使停机引脚处于低电平将驱动CXAR41274进入停机状态。

产品概述 返回TOP
The CXAR41274 is a mono audio power amplifier in 8 pin SOP-8, MSOP-8, SOP-8 (FD) or TDFN3X3-8 with thermal pad package. It can drive 2W continuous RMS power into 4Ω load in Bridge-Tied Load (BTL) mode at 5V supply voltage. Its THD is smaller than 1% under the above operation condition. For the low current consumption applications, the SHDN mode is supported to disable the CXAR41274 when it is idle. The current consumption can be further reduced to below 1μA. Giving the SHUTDOWN pin low level will drive the CXAR41274 entering the shutdown.
