I have a question on ADuM4190.
What is the input impedance of the ADuM4190?
I want input impedance to be 22kΩ or more.
Hi,I moved your question to its proper community Interface and Isolation.Regards,Goz
I will ask the designer for the value and get back to you.
Thank you for your reply
Now I am making an alternative proposal for an isolation amp.It seems that the customer is thinking that problems are occurring with the isolation amplifier currently being used and that factor is not the input resistance.Since the part currently in use has an input impedance of 22 kΩ, we would like to know the information of ADuM 4190.Is this information insufficient.
Baggio: The designer said the DC input resistance is high, greater than 1M ohm.
Thank you foro your reply.
