At the moment, no greater than V/10, however could go as high as V/30. Can't tolerate any reduction in input resistance since the input is from the DUT on an ohms converter, which could be 100M or more, hence it has to be non-inverting. This is just my route to being able to measure at significant voltage (ie, as high as this particular opamp can stand) across the DUT.
I figured out how to make a fully differential ohms converter but then discovered it needs a single sided mode as well, which is what this is for... <sigh>
