CXES4272是一种高密度、双极/双掷（DPDT）模拟开关，它允许-0.3V到+5.5V的信号在电源低于信号范围时无失真通过。低RON电阻（0.2W）使器件适合低失真开关，如音频。CXES4272具有内部分流开关，在常开（NO1和NO2）端子处放电音频放大器交流耦合电容。此功能可减少在预充电点之间切换音频信号时出现的咔哒声和弹出声。开关完全指定在单个+2.9V至+5.5V电源下工作。由于电源电流要求低，VCC可以由GPIO提供。不加电源时，开关进入高阻抗模式，所有模拟信号端口都能承受-0.3V到+5.5V的信号。这些设备用控制位CB控制开关。CXES4272有1.2毫米x 1.2毫米、0.4毫米间距、9凸点晶圆级封装（WLCSP）可供选择，工作温度范围在-4至+85摄氏度之间。

产品概述 返回TOP
The CXES4272 is a high-density, double-pole/ doublethrow (DPDT) analog switch which allows signals from - 0.3V to +5.5V to pass without distortion even when the power supply is below the signal range. The low RON resistance (0.2W) makes the devices ideal for low-distortion switching, such as audio. The CXES4272 has internal shunt switches that discharge the audio amplifier AC-coupling capacitance at the normally open (NO1 and NO2) terminals. This feature reduces click-and-pop sounds that occur when switching audio signals between precharged points. The switches are fully specified to operate from a single +2.9V to +5.5V power supply. Because of the low supply current requirement, VCC can be provided by a GPIO. When the power is not applied, switches go to a high-impedance mode and all analog signal ports can withstand signals from -0.3V to +5.5V. The devices control the switches with a control bit, CB. The CXES4272 is available in a 1.2mm x 1.2mm, 0.4mm pitch, 9-bump wafer-level package (WLCSP), and operate over the -4oC to +85oC extended temperature range.
