Abstract:
1. A D/A converter comprising: a first reference voltage; a second reference voltage; a plurality of resistors connected in series between the first reference voltage and the second reference voltage; and a plurality of switching elements; wherein the plurality of switching elements are controlled by an input digital data, wherein the plurality of switching elements extract a potential from selected one of connecting portions between the plurality of resistors, wherein the input digital data is a non-linear conversion digital signal, wherein the non-linear conversion digital signal is non-linear with respect to an original analog signal, wherein the potential is a linear conversion analog signal, wherein a resistance value of each of the plurality of resistors is set so that the non-linear conversion digital signal is directly converted to the linear conversion analog signal, and wherein the linear conversion analog signal is linear with respect to the original analog signal.
