Abstract: A signal output circuit is configured to control driving of an output transistor to output a trapezoidal wave output signal from a main terminal of the output transistor. The signal output circuit includes a driver that drives the output transistor at a constant current and a drive capability changing unit that periodically changes drive capability of the driver.
