our customer is facing some issues, where I would need some help:
"The problem with the opamp that we have is an offset voltage at the output when the differential input is short-circuited. This means that for example when we have zero voltage or current, we have a remaining voltage to the MCU. We managed to reduce this a lot, and we can compensate for it in the firmware.
This issue decreases our resolution since we cannot use all the bandwidth of 3.3V to represent 1kV, but only 3.3V-0.5V=2.8V. "
Could someone kindly have a look into this?
Many thanks in advance.
