摘要
我们在开发PC-1500微机为微弱信号放大及采集接口电路板中,对第四代集成运算放大器7650进行了比较详细的探讨。本文对该片的工作原理、特性及我们的使用经验进行了归纳性的介绍。
We have made an approach to application of 7650 operational amplifier in refom of conterminal circuit of PC-1500 microcomputer used to amplify and acquire the weak signal. In this paper, we introduced the principle of this kind of operational amplifier and its preformance.
