ABSTRACT:
A D/A converter has one single input transistor used in common with a plurality of output transistors to together form current mirrors, and a decoder serves to sequentially select the current mirrors in response to a digital input, causing to generate a corresponding analog output from currents from selected ones of the current mirrors. The commonly used input transistor is centrally located with respect to the current mirrors such that the difference between the maximum and minimum distances, or that between the maximum and minimum parasitic resistances, between the input transistor used in common and the output transistors is reduced and the conversion characteristic can be improved.
