AD8180与未缓冲的ADG601的区别

Category: Hardware

Product Number: AD8180 , AD818

如题，区别是什么？

如果模拟开关输入的是蓝色波形，绿色波形为开关信号，如何尽可能滤除两边的激波？

AD8180自带buffer，有一定驱动能力。

绿色如果是AD8180的SELECT信号，那么AD8180的输出看不到蓝色激波。

输出应该是绿色高电平期间的蓝色波形。

您好，我在使用的过程中还发现，在模拟开关开通的瞬间，输出电压信号相比输入信号来说有明显的过冲，这是由于开关速度太快导致的吗？还是什么其他原因，以及是否有解决方法？

地电平会出现类似于图中大小的波动，理论上可能导致误切换，有什么处理方法吗？
