摘要
文中对四种最为常用的模数转换(A/D)技术加以比较,重点介绍了∑-△技术的工作原理。同时介绍了串行输入输出的24位ADC芯片AD7710的基本特点,最后给出它与8051单片机的接口示意图。
In this article,key characteristics of the four most popular techniques for analog - to - digi-tal(A/D)conversion are compared. Also included are an in - depth review of the principle of Sigma-delta (Σ - Δ) architecture and the characteristic of a 24-BIT ADC AD7710. . At last we give the interface sketch fig of AD7710 with 8051.
