A capacitive array particularly for converters, comprising a plurality of unitary capacitors, the number of the unitary capacitors being equal to 2.sup.n, where n is the number of bits of the binary code required in output, the unitary capacitors being mutually connectable so as to obtain capacitors in which the capacitance ratio between one capacitor and the adjacent parallel-connected capacitor is equal to a factor of two. The invention is that the factor-of-two capacitance ratio of adjacent capacitors is achieved by mutually diagonally connecting in parallel the unitary-capacitance capacitors of the capacitive array in a preset number according to the capacitance value to be obtained.
