OPA2 Offset Configuration Value
This register contains the offset calibration value for OPA2. This field is set to the production OPA2 offset calibration value, hence
the reset value might differ from device to device. The field is sign-magnitude encoded. Higher values lead to lower OPA results.
The resolution of the LSB is 1.6mV/LSB
