A/D and D/A Converter Circuit Design Based on Proteus and Keil

Abstract: This paper introduces the Proteus and Keil software as a tool to AT98C51 chips and ADC0808 chips and DAC0832 chip as the basic module, through the design to the analog form into digital amount of A / D converter circuit and the ability to convert the analog digital The D / A converter circuit. The simulation shows that by Proteus design is feasible. These two circuits are mainly used as a computer and an external bridge between charged objects.
