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
·工作电压：2.4V~5.5V
·全差分AB类放大器
·高PSRR和优异的射频整流抗扰度
·低串扰
·VDD=5V时3W输出功率进入3W负载
