Hello,
On page 14 of the AMC1200 datasheet there is a diagram showing a voltage monitoring application.
I have a couple of questions regarding this:
1. What is the tolerance of the Rin resistor which is listed as 28kohm in the datasheet.
2. If I include the Rin resitance as part of my calculation for the voltage divider do I still get the extra gain error described by Equasion 1?
3. I am trying to monitor a voltage which is 280Vp, what is the best way to use the AMC1200 to keep the gain error as low as possible.
Thanks;
Leo
