The article is devoted to development of engineering applications in the form of a decision support system with an integrated database of the sigma-delta converters information. This problem is relevant in connection with the fact that because of their unique technical and metrological characteristics of today nomenclature produced integrated sigma-delta ADC is a few hundred units and growing. The main achievements in this field are due mainly to several foreign companies, of great interest is the analysis of structural and algorithmic solutions applied in their development. The authors collected information on the official internet resources in the industry's leading manufacturers of integrated circuits Analog Devices, Texas Instruments / Burr-Brown, Maxim Integrated Products of more than two hundred converters with delta-sigma architecture. The information collected is entered into the SQLite database, integrated in the developed application. This article describes the functionality of the decision support system for users of different skill levels. Accordingly, there are two modes: mode "Beginner" and mode "Expert". Mode "Beginner" can be used as an introductory reference book for students, graduate students and other professionals in the field of high-precision analog-to-digital conversion. In mode "Expert" selects the chip converters of this class with the ability to prioritize a search by interactive input weighting coefficient parameters. For experts proposed open form database with the ability to edit the information about converters with delta-sigma architecture. Screen forms are given to work with decision support system. Developed engineering applications can be used to select the electron-component basis, consistent with the requirements engineer in the design of complex functional blocks consisting of information-measuring systems.
