Hello, I have a question about SDADC. How can I understand and detect the health status of SDADC?

Could you clarify what exactly you have on your mind?

The SDADC gain calibration section of the MPC5777c reference manual contains the following information: If no gain, the expected gain error is 0.95(page 1077). My question is: What is the minimum and maximum value of gain error? For example, I calculated the gain error 0.5. Can I say that there is an error in the SDADC measurement by looking at this value?

Likewise, what are the minimum and maximum values of the offset value obtained in the offset calibration?  @davidtosenovjan

Following are specs without calibration what implies ranges of gain and offset errors could be
