Hi Sir:
I use the xtr111 change the V single to C single. But I find that. if have no load. the output normally. but if it be connected to 100Ohm load. Run a long time We find the output have a offset 0.2mA and It has nothing to do with the output current it means output i=4ma the offset is 0.2mA , output i=20mA the offset is also 0.2mA .Why.
