Abstract
An output circuit includes a drive signal output circuit for outputting a drive signal, an output stage circuit including a PMOS transistor of pull-up side connected between a power supply potential and an output terminal, and an NMOS transistor of pull-down side connected between the output terminal and a ground potential, gate of the NMOS transistor being connected to an output node of the drive signal output circuit, an output drive control circuit for outputting a signal to be supplied to the gate of the PMOS transistor of pull-up side, a feedback capacitor connected between the output terminal and the output node of the drive signal output circuit, and a potential limiter circuit for limiting an amplitude of the signal of the output node of the drive signal output circuit on the basis of the output voltage of the output terminal.
