I am trying to determine DC errors for ADC128S102QML-SP. More specifically, I am referring to the gain error, offset error, INL error, and DNL error. It is a 12 bit ADC with a supply voltage of 5V.

From the datasheet, I concluded the following:

  1. Offset error is 2.3 LSB which I believe translates to an error of
    (2.32/2^12) x 5 = 2.81mV

  2. INL is 1.4 LSB which I believe translates to an error of
    (1.4/2^12) x 5 = 1.71mV

  3. DNL is 1.5 LSB which I believe translates to an error of
    (1.5/2^12) x 5 = 1.83mV
Does the above calculations make sense? Also, how I can calculate the gain error?
