Description: 在做一个单片机系统时，常常会遇到这样那样的数据采集，在这些被采集的数据中，
大部分可以通过我们的I/O 口扩展接口电路直接得到，由于51 单片机大部分不带AD 转换
器，所以模拟量的采集就必须靠A/D或V/F 实现。下现我们就来了解一下AD0809与51 单
片机的接口及其程序设计。

Description: AD0809程序，ADC0809 是8 位逐次逼近型A/D转换器。它由一个8路模拟开关、一个地址锁存译码
器、一个A/D 转换器和一个三态输出锁存器组成（见图1）。多路开关可选通8个模拟通道，
允许8 路模拟量分时输入，共用A/D 转换器进行转换。三态输出锁器用于锁存A/D 转换完
的数字量，当OE 端为高电平时，才可以从三态输出锁存器取走转换完的数据。-AD0809 procedures, ADC0809 is an 8-bit successive approximation type A/D converter. It consists of an 8-channel analog switch, a latch address decoder, an A/D converter and a three-state output latch components (see Figure 1). Optional multi-pass switches 8 analog channels, allowing the volume of time 8-channel analog input, sharing of A/D converter to convert. Three-state output latch lock is used A/D conversion of the digital end, when OE is high-end only when the output from the tri-state latch data taken after the conversion.
