传感器输入

Circuit Protection of Transducer Input



设计说明:

保护应用:
传感器的输入端在病人和测量电路间形成一个界面。可存在ESD电气危害。
解决方案说明:
As shown at the left, a single multilayer varistor can be used to protect the sensor input.
配套解决方案:
For applications with multiple transducer and sensor circuits, the SP7x series of rail clamp arrays can be used.
监管问题:
IEC 61000-4-2是最适合此电路的标准规范。通过该测试可证明终端产品不易受到ESD危害。
特性:
不适用。
应用警告:
The signal frequency of the transducer input should be taken into account. For frequencies greater than 150MHz, the PulseGuard technology should be considered.
