摘要
通过将８２５３定时器／计数器引入Ａ／Ｄ转换电路，使其具有能任意设定并精确控制采样间隔的功能；通过将采样保持器设置在多路开关的前端，使电路具有同步采样的功能。
By using the 8253 timer/counter,the A/D convertor can accurately control the sample interval arbitrarily.By putting the sample and holding IC in front of the multiplexer,the convertor can also do synchronous sampling.
