PURPOSE: A switch driver for current-switching dac is provided, which is used in needing switch in complementary manner with accurately-controlled complementary switching signals. CONSTITUTION: Switch driver circuity having first and second output nodes with a current-voltage converter connected therebetween and providing current paths of first and second directions between the nodes, switching circuity connected therewith being switchable between first and second states respectively permitting current flow of a common preselected magnitude in respective first and second opposite directions producing potential differences between the first and second output nodes(ON1,ON2) of a common magnitude but respective, opposite polarities.
