Abstract
Provided is a switching circuit capable of transmitting a signal with large amplitude and large current while suppressing deterioration when a small-amplitude signal is transmitted. The switching circuitincludes a first terminal a, a second terminal b, a first switch, a second switch, a first separation switch, and a second separation switch. The first switchconnects the first terminal a and the second terminal b according to a control signal. The second switchhas a first node nand a second node n, and connects between the nodes in synchronization with the first switch. The first separation switchtransmits a signal of the first node nto the second node nwhen an electric potential of the first node nis higher than that of the second node nby more than a predetermined electric potential. The second separation switchtransmits a signal of the first node nto the second terminal b when an electric potential of the first node nis higher than an electric potential of the second node nby more than a predetermined electric potential.
