We are using the XMC4700 in high sampling rate 6-7ch, 4 groups.
When averaging many samples, we see different offsets (about +-0.3ADC steps) when rebooting the chip or when changing trig inputs on the ADC.
We beleve this has to do with the internal calibration of the ADC done on startup but why it also occurs when changing trig input on the ADC is more unclear.
Does anyone have similar issues or suggestion on how to understand what offset/calibration is applied in the current measurement?
Is it possible to deactivate the internal calibraiton (except the calibration flag on each conversion)?
Any input regarding this is of interest.
Thank you, Jacob
