MCS—51单片微机的12位A/D、D/A通道设计

12 Bits A/D, D/A Channel Design for MCS-51 Single Chip Microcomputer

MCS-51系列单片机是普及型单片机,芯片内不含A/D与D/A转换器。在实际应用中,由于许多对象是模拟量的,多数单片机应用系统不仅要处理数字量,还要处理模拟量。本文把8031单片机与ADC1210、DAC1210的接口电路及相应的程序设计作一介绍。

ACS-51 series of single-chip microcomputer is a popular one. There is no A/D and D/A converter in the chip. In practical applications, since large numbers of objects are analog, so most of the single-chip microcomputer operating system not only processes digital, but also analog, 8031 single-chip microcomputer and its interface circuits with ADC1210 and DAC1210, and the corresponding program are introduced in the paper.
