System of electronic microunits for applications in equipment for physical experiments

Main types of microunits used for amplification and conversion of detector signals in radiometric and spectrometric tracts are considered. Comparative analysis of main features of the microunits produced in the USSR with those of the foreign production is given. the microunit representd a functional unit constructed according to the hybride integral circuit technology. In this case thin film production practice, which permits to reach measuring accuracy up to 0.1%, is used. The main functional aim of the microunits if to provide the integration of measuring tracks of the devices with digital systems of signal recording, accumulation and processing, carried out on the basis of industrial integral circuits. Elements for selection and analog-to-digital conversion are introduced into the microunits. Today the electronic microunit system consists of two series: series 01 includes microunits for detector signal conversion, amplification and shaping, series 02 consists of microunits for signal shaping and measurement of their amplitudes. Functional independence of the microunits, their small sizes allow to increase parameters of the devices designed, to increase functional density of measuring channel arrangement
