PURPOSE:To form a D/A converter which can responds to a digital signal at high speed with high accuracy by providing a delay means delaying either a 1st input signal or a 2nd input signal to the D/A converter for a prescribed time so as to reduce glitch included in an output signal. CONSTITUTION:The D/A converter is provided with a delay means 3 delaying either a 1st input signal Din1 or a 2nd input signal Din2 for a prescribed time. Then the 1st input signal Din1 inputted to a control terminal of one transistor(TR) 1 being the component of a current switch is delayed by the delay means 3 for a prescribed time. Thus, just after the switching of the level of the 1st input signal Din1 is started, the signal level is switched at a signal level at which the level intersects the 2nd input signal Din2 and the current switch is easily operated. As a result, glitch included in the output signal is reduced markedly and the response characteristic of the output signal with a fast speed and high accuracy is ensured.
