We want to know the total error that is caused by ADC of INA226. (Not IC but ADC)

We found differential nonlinearity as +\-0.1LSB on the datasheet.

Is it OK to regard differential nonlinearity as the total error of ADC?

Should any other error elements be considered?

Hi,

The differential non-linearity is not the only error you may have to consider.

You may also have to consider the offset error, the gain error, the drift error, the VCM error or again the PSRR error depending on your application.

You can have a better idea on how are those error by watching those different videos:
