摘要
嵌入式双积分模数转换器因精度高、使用灵活、价格低廉而得到越来越广泛的应用。本文介绍了这种模数转换器在邮政专用电子秤中的应用情况 ,分析了通过改变正向积分时间扩展计量量程 ,提高计量精度的有效方法。使用结果表明该方法可行 ,有效 。
Embedded Dual Integration A/D Converter is used more and more wildly due to its high accuracy, flexibility and low cost. In this paper we explain how to use it to extend the full scale ranges and increase the accuracy for the postal electronic scale by changing the positive integral time. The results show that the method is feasible and very efficient.
