The present invention pertains to a method for controlling a D/A converter, a D/A converter, a method for controlling an A/D converter, and an A/D converter, with which an existing nth-order harmonic can be suppressed without using a large-scale circuit such as a bootstrap circuit. This D/A converter (10) is capable of suppressing the generation of an existing nth-order harmonic (where n is an integer of 2 or greater) of an analog output signal. The D/A converter (10) is equipped with a D/A conversion unit (11), which converts an input digital signal to an analog signal, and a control unit (12), which arbitrarily controls the timing of a sample phase and an integral phase of the D/A conversion unit (11). The D/A conversion unit (11) is configured so as to generate an arbitrary nth-order harmonic and superpose the arbitrary nth-order harmonic on an analog output signal having an existing nth-order harmonic.
