Abstract
An output circuit includes a first switch that outputs a positive voltage signal received via a first node when in an ON state, a second switch that outputs a negative voltage signal received via a second node when in an ON state, third and fourth switches that set the first and second nodes to a reference power supply voltage when in an ON state, a first voltage follower circuit that supplies a voltage obtained by shifting a voltage of the positive voltage signal supplied to the first node to a negative side by a predetermined voltage difference to a gate of the first switch, and a second voltage follower circuit that supplies a voltage obtained by shifting a voltage of the negative voltage signal supplied to the second node to a positive side by a predetermined voltage difference to a gate of the second switch.
