ABSTRACT:
A digital-to-analog (DA) converter includes a detector for detecting an input sampling frequency of digital data using a sampling clock and a master clock, an oversampling digital filter for oversampling the digital data on the basis of the input sampling frequency, an input sampling frequency change detector for detecting a change in the input sampling frequency, and a mute control for muting the data to be DA-converted on the basis of the detection result of the input sampling frequency change detector.
