FIELD: measurement equipment.
SUBSTANCE: device comprises a scaling device, made with a fixed set of transmission ratios, an analogue-to-digital converter with a fixed range, a device for subrange selection, the number of comparators of which is selected less by a unit than the number of subranges, a code converter.
EFFECT: provision of the possibility for efficient change of transmission ratios of a scaling device of an analogue-to-digital converter with expanded dynamic range depending on the level of converted voltage and generation of an output code, corresponding to the set transmission ratio.
