用AD650作PC-XT的A/D转换接口电路

Interface Circuit Using AD 650 as PX—XT Interver

介绍V/F转换器AD650的工作原理,并且提出了一种基于AD650进行模数转换的新型结构的数据采集系统。本系统兼有模拟量输入通道隔离功能,可以远距离传递信号,可按用户要求实现10bit—16 bit不同精度要求的A/D转换,可直接与PC机及其相兼容各种机相连接.

This paper mainly introduces V/F inter AD 650 basis work theory and puts forward a sort of new data collecting system based on AD 650. Its advantages are that it has this function of analogy in- put channel isolation and long distance signal transmission, demanded by the user, it may realize 10 bit～16 bit different precision A/D interver and directly join with PC computer and all kinds of corresponding computers.
