Abstract: Provided is a pulse density modulation value converter, comprising: a pulse density modulation reference point storage for storing a plurality of pulse density modulation reference points, each pulse density modulation reference point comprising a linear pulse density modulation value, an actual pulse density modulation value and/or an integral non-linear error value, wherein the integral non-linear error value is the difference between the actual pulse density modulation value and the linear pulse density modulation value; and a pulse density modulation value calculator for receiving a linear pulse density modulation value, searching the pulse density modulation reference point storage for a pair of pulse density modulation reference points closest to the linear pulse density modulation value, obtaining an actual pulse density modulation value corresponding to the linear pulse density modulation value through linear interpolation on the basis of the pair of pulse density modulation reference points, and outputting the actual pulse density modulation value.
