摘要
本文介绍了高精度线性光耦器件HCNR200/201的主要特性及工作原理,并分析了一个使用该器件的模拟信号隔离转换的典型电路,它可将输入4～20mA电流信号隔离转换成电压信号。
This paper introduces the features and theory of operation of the high-linearity octocoupier HCNR200/201. It also analyses a signal conditioning circuit, which shows how to implement the 4-20mA analog current-loop transmitter and receiver circuits using this optocoupler.
