      Hi GHOZLANI, Thanks for this. The result truly looks anomalous. Based on your circuit and the datasheet, there really shouldn't be any problem; the expected output should indeed be close to 1.24V (even considering the offset voltage). We concur that this issue might be caused by external variables …
