FIELD: electricity.
SUBSTANCE: device comprises code converter, seven multiplying linear digital-analog converters, source of reference voltage and summator, besides the first three multiplying linear digital-analog converters perform non-linear polynomial conversion, and remaining four multiplying linear digital-analog converters with the help of code converter realise alternating coefficients depending on interval of approximation in this polynomial conversion.
EFFECT: simplified scheme of functional digital-analog converter and improved accuracy of digital-analog conversion.
