The development of technologies currently predisposes to the use of the method of adsorption separation in the analysis of multicomponent mixtures in many industries and the national economy and is gradually replacing traditional chemical and physicochemical methods. Obtaining highly pure substances with a percentage of trace impurities less than 10-6% is possible only when using an adsorption unit with a large number of columns used. The efficiency of adsorption methods is significantly increased due to the automation of data processing at the outlet of the adsorption plant. The automation process includes pairing the adsorption unit with a personal computer and for this it is necessary to use such devices for processing signals at the output of the adsorption unit, such as amplifiers, analog-to-digital converters. This article is devoted to the design and development of an instrumentation amplifier with automatic scaling and a digital comparator that provides switching gains. The article discusses the calculation and development of a digital comparator for an instrumentation amplifier with auto scaling. A detailed selection of the type of analog-to-digital converter is presented, the choice of which took into account the frequency, cost and error of the existing types used for processing signals at the outlet of the adsorption plant.
