摘要
介绍一种利用运算放大器对非线性光耦进行补偿使之具有线性传输特性的隔离放大器,对其工作原理进行了分析,并给出了实测结果.
线性光电耦合隔离放大器In industrial measuring and controling system, it is usually needed to transmit analog signals without connected ground wire. This paper introduces an isolated amplifier, which has a linear transmitting characteristic by using operational amplifier to compensate the non-linear characteristic of photo - electric coupler, analyses its principle and gives its test data.
