Abstract
An output circuit includes a connection switch and an operation unit. The connection switch receives first and second voltages from first and second terminals, respectively, selects and outputs the first voltage or the second voltage for first to third intermediate terminals, including selection of the same voltage and switches assignment of the first and second voltages to the first to third intermediate terminals responsive to a connection switching signal. The operation unit receives the voltages assigned to the first to third intermediate terminals and outputs to an output terminal a voltage obtained by performing a predetermined operation on the voltages.
