给出信息的电压形式从模拟量到数字量精确转换所依赖的基础———Ａ／Ｄ界面。揭示构成各类分时段并行Ａ／Ｄ转换器量化界面基础性、共通性的各种要素性电路环节，对Ａ／Ｄ量化界面电路进行全面整体数学抽象。在此基础上，给出分时段并行Ａ／Ｄ转换精度理想量化数学模型，指明Ａ／Ｄ界面电路全体相关因素的各种函数关系。

This paper, from a theoretical point of view, presents the concept of A/D interface, upon which the accurate conversion of the information of the voltage form from analog to data is based. It explores the basic, common and key circuits which form different kinds of time division and parallel A/D converters, and gives a comprehensive mathematics abstract of the whole A/D interface. On this basis, it presents a mathematics model of accurate time division and parallel A/D converters, thus explaining functions of the factors in the A/D interface and pointing out a way for further research.
