Zusammenfassung:	According to an embodiment of the present invention, a digital-analog conversion device comprises: a signal modulation unit configured to modulate an inputted first digital value to a signal in which a second digital value, of which a bit number is smaller than the first digital value, is periodically changed; and a digital-analog conversion unit configured to convert the second digital value into an analog value. Digital-analog conversion with high resolution can be performed by using the digital-analog conversion unit with low resolution. 본 발명의 일 실시예에 따른 디지털-아날로그 변환 장치는, 디지털-아날로그 변환 장치는 입력된 제1디지털 값을 제1디지털 값보다 비트 수가 적은 제2디지털 값이 주기적으로 변하는 신호로 변조하는 신호변조부; 및 제2디지털 값을 아날로그 값으로 변환하는 디지털-아날로그 변환부; 를 포함함으로써, 저해상도의 디지털-아날로그 변환부를 이용하여 고해상도의 디지털-아날로그 변환을 수행할 수 있다.
