Abstract
A glitch occurrence prevention circuit for a digital/analog converter comprising semiconductor switching means which is turned on or off in relation to a level between a digital input voltage and a set threshold voltage, but having inconsistent timing of being turned on and off in response to the digital signal due to a switching characteristic of different rise and fall times, the glitch occurrence prevention circuit having means to normally provide a predetermined bias voltage to the digital input of the digital/analog converter so that the timing of turning on and off the semiconductor switching means is consistent.
