2021918 · There does not seem to be a pattern to the data: one result is too high, the other too low. A few more questions: Can you double check that the readback for the 5V measurement is 0xA6 7707 E9 and not 0x46 7707 E9? Do you have access to measure the reference voltage on REFIN? It would be good to confirm that the reference is correct.
