CXAR4180是一款立体声、固定增益、单电源和无盖耳机驱动程序,可在WLCSP1.6x1.6-12和TDFN3x3-12软件包中提供。CXAR4180是接地参考输出,不需要输出电容器进行直流闭锁。消除输出电容器的优点是节省成本,消除元件高度,提高低频响应。内部固定增益设置(-1.5V/V)可以最大限度地减少外部元件数量,节省PCB空间。高PSRR提高了对噪声和RF整流的抗扰度。CXAR4180能够在3.6V电压下将50mW驱动至16W负载,并提供热保护。
·工作电压:2.3V~5.5V
·供电电流-VDD=3.6V时,I DD=1mA
·低关断电流-VDD=3.6V时I DD=5mA
·接地参考输出
-无需输出电容器(用于直流闭锁)
-节省PCB空间
