产品简介

CXAR4184是一款单声道、全差分AB类音频放大器，可在2.4V至5V的电源电压下工作，并提供MSOP8、MSOP8P或TDFN3x3-8封装。内置反馈电阻可以减少外部元件数量，节省PCB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CXAR4184成为移动电话和便携式设备的理想选择。ACXAR4184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嗒声。热保护和过流保护都集成在一起，以避免集成电路因过热和短路而损坏。ACXAR4184能够将5V的3W驱动到3W扬声器中

   产品概述 返回TOP

The CXAR4184 is a Mono, fully differential Class-AB audio amplifier which can operate with supply voltage from 2.4V to 5V and is available in MSOP8, MSOP8P, or TDFN3x3-8 package. The built-in feedback resistors can minimize the external component count 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 startup time and small package size make the CXAR4184 an ideal choice for Mobil Phones and Portable Devices. The CXAR4184also 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 to be destroyed by over temperature and short-circuit. The CXAR4184is capable of driving 3W at 5V into 3W speaker
