摘要
文中介绍了光电耦合器的基本原理及其特性,分析了用TIL117型光电耦合器及经过精选的741运放组成传输模拟信号的实用电路,提出了解决高抗共模电压及高精度测量时,使用光电耦合器作隔离的一个可行方案。
Automation Instrumentation. -1989, 10(7). -8～12 The basic principle and features of the photo coupler are introduced. The practical circuit composed of TIL117 coupler and well selected 714 operational amplifier for transmission of analog signals is analyzed. A feasible strategy using photo coupler with high common rejection and high measuring accuracy is stated.
