ABSTRACT:
There is provided an array device including functional circuits for a plurality of channels, constant current generating circuits for the plurality of channels for generating constant currents used to drive the functional circuits, respectively, in accordance with a control signal supplied from the outside, and a wiring for supplying therethrough the constant currents from the constant current generating circuits to the functional circuits, respectively, which are formed on an integrated circuit chip, wherein the constant current generating circuits provided so as to correspond to the channels are arranged concentratedly in a specific region on the integrated circuit chip, and the wiring is comprised of a common wiring extending from one terminal provided in the vicinity of the specific region to the vicinities of the constant current generating circuits.
