Abstract
This paper presents a design method of DC source based on AT89S52, the reference voltage of LM336 is divided into 256 by DAC0832, the regulation of output voltage is achieved by changing the input of DAC0832, and the output voltage is magnified by the amplifying circuitry and LM317. For the stabilization, ADC0809 output is fed back to the AT89S52.
