<p>PROBLEM TO BE SOLVED: To provide a control device of output voltage value which eliminate the control work of output voltage value accompanying the scattering of characteristics that constituting parts have. SOLUTION: The control device of output voltage value processes input signal and outputs a voltage made a desired proportional relation to the input signal through a D/A converter 6 and an amplifier 7. It is provided with a reference voltage generator 1 generating a reference voltage, an A/D converter 2 A/D-converting the output terminal voltage according to the reference voltage generated by the reference voltage generator 1, a control value calculator calculating a correction coefficient by using the desired output terminal voltage against the output signal of the A/D converter 2 and the reference voltage and the reference voltage, a memory 4 storing the correction coefficient calculated by the control value calculator 3 and a signal processor 5 reading the correction coefficient from the memory 4 and calculating the correction value using the input signal and the correction coefficient, and outputs the correction value through the D/A converter 6 and the amplifier 7 to the output terminal 8.</p> |
