摘　　要：介绍了一种不增加A/D转换单元电路板面积却能加倍扩展模拟输入通道数量的创新设计方法-IC(集成电路)层叠并联。相关技术获中国国家专利。本文给出了以MCS-51和ADC0804接口为典型的硬件、软件设计实例。A new design,overlay and parallel connection of IC,is introduced in this paper. This technology can multiply extend the channel of A/D converter without increasing the area of its unit circuit board. This technique has been applied successfully and gained the authorization of China nationtl patent. Samples of hardware and software are given based on MCS-51 and ADC0804.
