高速同步数据采集卡设计

A Circuit for High-speed Simultaneous Sampling

提出了一种数据采集卡的设计方案 ,应用maxim的A/D芯片MAX12 5实现了 8通道高速同步采集。预处理电路、A/D转换和FIFO缓存集成在同一块电路板上 ,组成一个功能比较完善的模块 。

This paper presents a circuit for 8 channels simultaneous sampling,on which the MAXIM company's IC MAX125 is applied.Pretreatment circuit,A/D converter and FIFO buffer are integrated on a printed circuit board(PCB).The circuit can be applid on state monitoring system of rotating machine.
