Hello,
We are working with the MSP430FR5969-SP and were having a tough time understanding the following.
- The datasheets and application notes explain that the ADC can be calibrated to the initial accuracy of the internal or external reference. There was also mention of the factory calibration keeping it within 0.5 LSB. The accuracy of the internal reference is shown to be 1.5%. Is the assumption that this is the initial accuracy, and that the ADC can be calibrated to that value within 0.5LSB?
- Is factory calibration an option? Or are all chips calibrated out the door?
- We were unable to find drift information. Is there accuracy, or bias drifting vs time we could reference? Is there a burn-in time to help speed up that initial drift to get it to a more stable value?
Thanks.
