Abstract:
This signal output circuit (3, 51, 62, 74, 82) controls the driving of an output transistor (T1, T71, T72, T81 through T86) to output a trapezoidal-wave output signal from a main terminal of the output transistor. The signal output circuit is provided with a drive part (4, 75, 76, 83 through 88) for driving the output transistor with a constant current and a driving capability changing part (5, 64, 77, 89) for periodically changing the driving capability of the drive part.
