In (AD5421) TUE = Gain + Offset + output drift over temperature + INL
We can remove gain and offset error as per datasheet.
So after doing this TUE = output drift over temperature (5ppm FSR /°C ) +INL (0.024% FSR) for A grade (AD5421ACPZ)) and internal Rset resistor
Please confirm whether my understanding is correct.
If yes that means; whether I have to go with C grade ( AD5421CREZ) wherein INL is very less (0.0035% FSR). Please confirm.
Please clarify with confusion regarding grades.
