Abstract
A driving apparatus comprises switches SW to Sw , a first signal line OUTA, and a second signal line OUTB. By ON/OFF control of the switches SW to Sw , the voltage of the first signal line OUTA is changed between a positive voltage (+1/2V) level, which is smaller than a voltage V to be applied to a load , and the ground level, and the voltage of the second signal line OUTB is changed between the ground level and a negative voltage (−1/2V). By ON/OFF control of switches SW and SW , the positive and negative voltages given by the first and second signal lines are selectively applied to the load . The maximum voltage applied to each element in the driving apparatus can be thereby lowered to the voltage (1/2V), which is smaller than the voltage V to be applied to the load . This makes it possible to hold down the breakdown voltage of each element to half the conventional value.
