| 摘 要： | 本文简要介绍按钮式数字电位器X9511的基本原理。为了使调节更准确方便、精确改变电阻的大小，采用防抖触发器和单稳态电路防止抖动和重复动作。以及在ADC0809中，用数字电位器取代传统的机械电位器，使输入的模拟量精确可调，AD转换后输出的数字量更准确。

| Abstract: | This paper briefly discusses the basic principle of push button controlled digital potentiometer X9511.In order to regulate the resistance more accurately,the preventative dithering trigger and monostabillity circuit are adopted to prevent dithering and repeated actions.And in ADC0809,digital potentiometer is used to replace traditional mechanical potentiometer so that the anolog input can be more precise and adjustable and the output data more precise after AD conversion. |
