随着集成电路的发展,A/D转换芯片,采样保持电路和多路模拟开关已成为普通商品。为此,应针对A/D转换通道的技术要求,合理地选择系统结构,并按一定的技术、经济准则,恰当地选择所需集成电路,并根据它的使用说明,设计相应的接口电路,使A/D转换通道与计算机连接起来。在硬件设计的同时还必须考虑驱动程序设计,这样才能充分发挥硬件╱系统的功能。由于不同系统的驱动程序是建立在硬件基础上的,故此处所讲的系统设计方法仅涉及硬件部分。
With the development of integrated circuits, A / D conversion chips, sample-and-hold circuits and multiplexed analog switches have become common products. To this end, A / D conversion channels should be for the technical requirements, a reasonable choice of system structure, and in accordance with certain technical and economic criteria, the appropriate choice of integrated circuits required, and according to its instructions, the design of the corresponding interface circuit, Connect the A / D converter to the computer. In the hardware design must also consider the driver design, so as to give full play to the hardware / system functions. Since drivers for different systems are built on a hardware basis, the system design approach described here involves only the hardware part.
