Abstract. The use of micropower electronic devices in the construction of electronic equipment is a promising direction to improve its operation reliability. Reducing energy consumption and maintaining the required technical parameters of electronic devices are mutually exclusive requirements, therefore it is necessary to evaluate their effectiveness based on certain criteria. To assess the efficiency of micropower operational amplifiers, comparators, reference voltage sources and analog-to-digital converters, their basic properties and parameters are considered. A comparative analysis of the main parameters of foreign and domestic microcircuits is carried out. Criteria are presented for the efficiency of micropower electronic devices that take into account the minimum energy consumption without deterioration of their main characteristics, as well as minimization of structural complexity and simplification of construction schemes. For construction of micropower electronic devices several recommendations are formulated for selection of elements improving the device reliability, economy, and autonomy of the operation of the electronic equipment while reducing the specific material consumption and energy consumption. 
Keywords: operational amplifiers, micropower comparators, reference voltage sources, analog-to-digital converters, specific power consumption, specific current, specific energy value
