Hi ADIexpert
I would like to use the refout1 of ADUM4190 as a voltage reference to my other circuits in the schematic
I connected the REfout1 to the non invert pin of a TL074 to build a voltage follower without attaching any loading on the output of TL074…
Today, I had the same problem.I read your reply, but I still don't understand.What I want to ask is,how to use ADUM4190 as voltage follower?how to design the circuit?Looking forward to your reply.
Hello
Could you teach me about the input voltage range of ADUM4190 ?
I can not find the description of input voltage range in the datasheet.
I thought that input voltage range of ADUM4190 means input common mode range (0.35V~1.5V) desiceibed in the datasheet…
我需要从+IN输出0-5V,使用ADuM4190作为电压跟随器,是的EAOUT获得相同的输出,但是经过实际电路焊接测量,始终得不到作为电压跟随器的输出,因此想请教我的问题出在了那里? 我该怎么做才能实现这样的电压跟随器的输出呢? 谢谢,期待回复
Hi
I have a question on ADuM4190.
What is the input impedance of the ADuM4190?
I want input impedance to be 22kΩ or more.
