FIELD: electricity.
SUBSTANCE: method is implemented by introduction of auxiliary units of weighing dividing capacitors with keys identical to the main unit of weighing dividing capacitors with keys, at that capacitance of the smallest capacitor in each auxiliary unit is not equal to doubled capacitance of the biggest capacitor in the main unit or the previous auxiliary unit of weighing dividing capacitors with keys, and outputs of the above auxiliary units are joined with the output of the main unit of weighing dividing capacitors with keys.
EFFECT: reducing required space for ADC chip and consumed power due to reduction in total capacitance of the capacitors set.
