Part Number: FDC2214 您好,我一个三板电容器,电容从6pF 到10pF 变化,电感选择5.7uH,计算获得19sps下,22位精度(通过FDC_Tools-development5.xlsx计算),如下图
表格中有一句描述,Note that the resolution calculations are optimum device limitations may not be realized by the system
从数据表中描述,100sps下0.3fF噪音。我想咨询是否有5sps和10sps的噪音数据…
Part Number: FDC2214EVM Other Parts Discussed in Thread: FDC2214 问题1:在这篇文章Capacitive Sensing: Direct vs Remote Liquid-Level Sensing Performance Analysis使用FDC2214EVM板卡时,外接了4路导电电极片,请问这4个电极片是什么接法?
问题2:在使用FDC2214中,如果我的外接电极片使用单端的接法没有GND会有什么影响吗?
Part Number: FDC2214 We have discovered that some FDC2214 sensor boards in our mass-produced products are ubstable. it confused me! What aspects should I consider to locate this problem.
Part Number: FDC2214FDC2214 collects mutual capacitance. Why does the capacitance increase when people approach? This is not consistent with the paper, but when I use WK6500B impedance analysis to detect, the capacitance decreases. Is this the reason…
