| 摘 要： | 单片机内嵌式Ａ／Ｄ的使用要比外置式Ａ／Ｄ简单、方便，且容易获得更高的信噪比，但其分辨力相对比较低，难以满足精密测量的使用要求。本文介绍了一种提高单片机内嵌式Ａ／Ｄ转换器分辨力有效实用法，简单外转电路和单片机内部软件计算可以将原分辨力将提高１￣３倍。

| Abstract: | Compared with the peripheral A/D conversion device with one built inside the Single\|chip,computer is much more simple and convenient for use.And it is easy to get high signal to noise ratio.But the resolution is always not high enough to satisfy the requirement for precision measurement.A practical effective method for enhancing the resolution of A/D conversion device built inside the single\|chip computer is proposed in this paper,which can increase the orignal resolution by 1~3 times only with simple peripheral circuit and internal software calculation. |
