PROBLEM TO BE SOLVED: To provide a data processor for correcting an error caused when converting digital data (D) to analog data (A) by using a D/A conversion device (D/A converter), in which the degradation of accuracy due to temperature change is small or accuracy degradation is prevented. SOLUTION: The data processor is for processing the digital data inputted to the D/A conversion device for converting the digital data to the analog data. The data processor is constituted of hardware which processes the digital data so as to approximate processing executed output data which are output data based on the analog data converted by the D/A conversion device to target data which are true analog data represented by the digital data.
