CXAS42214是一种高速单片8:1模拟信号多路复用器。根据3位二进制地址行（A0、A1和A2）的确定，CXAS42214将8个输入中的一个切换到公共输出。EN输入启用或禁用设备。禁用时，所有通道都将关闭；启用时，每个通道在两个方向上的传导都一样良好，并且具有延伸到电源的输入信号范围。
这些开关的24Ω导通电阻和12Ω导通电阻平坦度使它们成为低失真至关重要的数据采集和增益开关应用的理想解决方案。
•24Ω典型接通电阻
•12Ω电阻平坦度
•±3.3V至±6.6V双电源操作
•3.3V至13.2V单电源操作
•-3dB带宽：80MHz
•轨对轨运行

产品概述 返回TOP
The CXAS42214 is a high speed monolithic 8:1 analog signal multiplexer. The CXAS42214 switches one of 8 inputs to a common output, as determined by the 3-bit binary address lines (A0, A1 and A2). An EN input enables or disables the device. When disabled, all channels switch off; when enabled, each channel conducts equally well in both directions and has an input signal range that extends to the supplies.
The 24Ω on-resistance and 12Ω on-resistance flatness of these switches make them ideal solutions for data acquisition and gain switching applications where low distortion is critical.
The CXAS42214 is available in Green TSSOP-16 package. It operates over an ambient temperature range of -40℃ to +85℃.
