【摘要】 按钮式控制数字电位器X9511由延时去抖动电路、单稳电路、触发器组成。采用防抖动触发器和单稳电路防止抖动和重复动作。用X9511电位器代替机械电位器可增加或减少电位器低端位置的滑动,得到准确的调节模拟输入量,以提高AD转换后的输出数字量。更多还原

【Abstract】 Button control digital potentiometer X9511 is consists of time delay circuit removed dithering, mono- stability circuit, preventative dithering trigger. The preventative dithering trigger and mono-stability circuit was adopted to prevent dithering and repeated actions. Digital X9511 potentiometer was used to replace traditional mechanical potentiometer, it can increase or reduce low end gliding resistance of potentiometer, and analog input quantity is adjusted accurately to improve output digital quantity after AD conversion.更多还原
