Many bit-ization also offers the semiconductor device which suppresses increase of chip size. Part voltage of the voltage produced between potential VH and potential VL is carried out, high electric strength digital to analog converter 1 in which an output of either of plural potentials 3 - 9 produced with part voltage based on the input signal (D 0 -DN- 1 ) is possible, plural elements 11 and 13, output elements 15, it has level shift part 17 which carries out the level shift of the potential of an input signal to potential required in order that output elements 15, plural elements 11, and each of 13 may operate, and impresses it to it. grouping of plural potentials 3 - 9 is carried out to the order of a potential level at plurality, the voltage between the potentials of the group which provides and corresponds corresponding to each group is applied, and each of plural elements 11 and 13 operates. either of the potentials in the group which corresponds based on an input signal is outputted, the voltage between VH and VL is applied, and output elements 15 operate, and output either of the potentials in which the output of plural elements 11 and 13 is possible based on an input signal.
