摘  要：本文主要介紹以Proteus和Keil作為工具軟件，以AT98C51芯片和ADC0808芯片以及DAC0832芯片作為基礎(chǔ)模塊,通過設(shè)計(jì)構(gòu)成能夠?qū)⒛M量轉(zhuǎn)換成數(shù)字量的A/D轉(zhuǎn)換電路和能夠?qū)?shù)字量轉(zhuǎn)換成模擬量的D/A轉(zhuǎn)換電路。通過Proteus的仿真可知該設(shè)計(jì)方案是可行的。這兩種電路的主要用途是作為計(jì)算機(jī)和外部被控對(duì)象之間的一種橋梁。

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.
