ABSTRACT:
The invention provides a multichannel drive circuit by which, even when there occurs a variation between channels in circuit characteristics of each channel including current source due to the semiconductor manufacturing process and the like, loads of each channel constituting a load array can be driven under conditions uniform between all the channels. The invention includes; an interchannel common connection line (5) for making conduction between respective current paths of each channel for connecting the respective current sources of each channel constituting a current source array (11) with respective input switches of each channel constituting an input switch array (13); and current blocking means (12) for blocking output current of the current source of that channel of the plurality of channels in which the input switch is in an OFF state from flowing into the interchannel common connection line.
