摘要
在分析传统直流信号采集电路设计问题的基础上,提出一种基于对模拟开关的控制来实现直流信号隔离式输入和断开的电路,并介绍了这种直流信号采集电路的原理和实现方法。
On the basis of analyzing the problems in traditional DC signal acquisition circuit design,a new DC signal acquisition circuit based on analog switch which is used to coutrol the DC signal's input and cutoff was suggested,and its principle and implementation method were presented.
