PROBLEM TO BE SOLVED: To provide an integrator, a digital-analog conversion circuit and an audio output system that can avoid generating a shock sound even if a random signal such as white noise is input.SOLUTION: An integrator 41 includes: a delayer 41a for delaying an input signal by one sampling period; an adder 41b for adding the delayed input signal to the input signal at the next sampling; and an overflow prevention circuit 41c for preventing the delayer 41a from overflowing. |
