CXES4274是便携式多媒体设备的音频点击和弹出消除器。从1.7伏工作到3伏。6V电源，CXES4274连接到现有系统放大器的输出，并在启动和关闭期间提供低阻抗接地路径。输入INL和INR接受电压从VDD波动到低于VDD的5.5V。有关更多信息，请参阅设置电源电压部分。上电和下电瞬态被分流到地面，以防止发出咔哒声和砰砰声。CXES4274具有两个由静音控制的低阻抗模拟开关，可打开和关闭开关。开关在正常工作时打开，对输出信号没有影响。在放大器的启动和关闭过程中，可以激活CXES4274，使输出对地短路，防止咔哒声和砰砰声通过耳机拉电流。
电源电压范围从1.7V到3.6V
·低静态电流1毫安
·通过设定销可调整关闭时间
·快速开启时间：100us（典型值）
·低开关电阻：0.3W
·无失真，点击和弹出消除
