产品简介

CXAR4191是一款立体声、全差分AB级音频放大器，可在2.4V至5V的电源电压下工作，并提供TQFN5x5-20A封装。内置反馈电阻可以减少外部元件的数量，节省PCB的空间。高PSRR和全差分结构提高了对噪声和RF整流的免疫力。除了这些功能，短的启动时间和小的封装尺寸使得CXAR4191是液晶电视、笔记本电脑和便携式设备的理想选择。CXAR4191还集成了防弹出电路，可减少电源开/关和关机模式操作期间的弹出声和咔哒声。热保护和过流保护都集成在一起，以避免集成电路被过温和短路损坏。ACXAR4191能够将5V的3W驱动成3W扬声器

   产品概述 返回TOP

The CXAR4191 is a stereo, fully differential Class-AB audio amplifier which can operate with supply voltage from 2.4V to 5V and is available in a TQFN5x5-20A package. The built-in feedback resistors can minimize the external component counts and save the PCB space. High PSRR and fully differential architecture increase immunity to noise and RF rectification. In addition to these features, a short start-up time and small package size make the CXAR4191 is an ideal choice for LCD TVs and notebook PCs and Portable devices. The CXAR4191also integrates the de-pop circuitry that reduces the pops and click noises during power on/off and shutdown mode operation. Both Thermal and over-current protections are integrated to avoid the IC being destroyed by over temperature and short-circuit. The ACXAR4191is capable of driving 3W at 5V into 3W speaker
