N2 - A high-precision digital control DC power supply based on singlechip STC89C52, A/D converter AD7705, D/A converter DAC7512 and three terminal adjustable regulator LM317 is designed and realized, which uses MCU as the center, and adopts 12 DAC DA7512 to realize digital control and 16 ADC AD7705 and LCD to the measurement and display of output voltage. The voltage adjustment range of this system is 0-13V, and the deviation of display value and set value is not more than 1%, voltage step value is 0.01 V. The experimental result shows that the system can well solve the accuracy of output adjustable voltage, and is characterized by high precision, easy to use and simple circuit.
