Well, AFAIK, LMS6002D doesn't have a temperature sensor built in and
this means we have to install an external one, which again increase
BoM cost. Is that's how this issue is solved by your other customers?
I wonder is there a way to solve this without introducing a
temperature compensation loop.
Let me clarify - DC offset re-calibration is (more or less) fine in
lab setup, but it's expensive to manufacture if we have to add
temperature sensors and put every unit into a temperature camera for
calibration.
