Background. At the present time integrated data converters with ΣΔ-architecture are the most mass types of electronic component base abroad. In Russia, interest in developing complex functional blocks based on ΣΔ-conversion of information is connected with the implementation of the federal target program "Development of Electronic Component Base and Radio Electronics " in 2008-2015. The aim of this work is to identify the perspective directions and regularities in production of data converters by industry-leading corporations such as Analog Devices, Texas Instru-ments, Maxim Integrated Products.
Materials and methods. According to classification signs (integrator type, modulator order, number of cascades, quantizer level) the authors collected information on 242 chips: 116 – Texas Instruments/Burr-Brown, 93 – Analog Devices, 33 – Maxim Integrated Products. The circular chart illustrating volumes of release of chips with ∑∆-architecture during the period 1996-2013 years is constructed. The article includes calculation in percents of a number of Front-End’s, converters with a continuous integrator, multichannel converters.
Results. The authors revealed the ependence of an effective number of bits on integrator type (continuous, continuous - discrete). The dependence of linearity of transformation on quantizer level (one-bit, multibit) was also designated. The authors proved a small number of produced multicascade structures and showed the importance of the digital filter-decimator as a part of the converter.
Conclusions. At the present time, taking into account high linearity Σ∆-modulators and achievements of MEMS technology, the increasing consumers’ and producers’ popularity is won by the Front-End's. The market finally is taken by Σ∆-converters with continuous and discrete integrators. Another tendency of development of the market of Σ∆-converters is the growth of channels number of signals transformation with the enclosed function of scaling thereof. New there occurs a ten-dency of using multicascade filters of high order (sinc4, sinc5), and also digital filters with the combined structure.

Key words

∑∆-ADC, ∑∆-modulator, ∑∆-architecture, data converters, continuous-time integrator, discrete-time integrator, order of modulator, level of quantizer.
