产品简介

CXAR4187是一款无滤波器的单声道D类音频放大器，可在WLCSP封装中使用。增益可以通过外部输入电阻设置。高PSRR和差分架构提高了对噪声和RF整流的免疫力。除了这些功能外，CXAR4187的启动速度快、封装体积小，是蜂窝手机和PDA的理想选择。CXAR4187能够在5伏电压下驱动1.3瓦或在3.6伏电压下驱动600兆瓦至8瓦。ACXAR4187也能够驱动4瓦。CXAR4187采用D级架构设计，与AB级放大器相比运行效率高。它适用于电源敏感的应用，如电池供电的设备。filterfree架构消除了输出滤波器，减少了外部组件数量、板面积和系统成本，并简化了设计。CXAR4187提供热保护和过电路保护

   产品概述 返回TOP

The CXAR4187 is a mono, filter-free Class-D audio amplifier available in a WLCSP package. The gain can be setting by external input resistance. High PSRR and differential architecture provide increased immunity to noise and RF rectification. In addition to these features, a fast startup time and small package size make the CXAR4187 an ideal choice for both cellular handsets and PDAs. The CXAR4187 is capable of driving 1.3 W at 5 V or 600 mW at 3.6 V into 8 W. The CXAR4187is also capable of driving 4 W. The CXAR4187is designed with a Class-D architecture and operating with highly efficiency compared with Class-AB amplifier. It's suitable for power sensitive application, such as battery powered devices. The filterfree architecture eliminates the output filter, reduces the external component count, board area, and system costs, and simplifies the design. The CXAR4187provides thermal and over circuit protection
