How to consider ADC Error Calculation?

Hi,

I trying to do an worst case error estimation in my ADC readings and according to the Datasheet as shown below I’ve other error factors Offset, Full- scale, Absolute Accuracy, DNL, INL.

We’re trying to mitigate the Offset and Full- scale error by applying a Two-Point Calibration Method.

I would like to know do I need to consider Absolute accuracy as ± 2 even though I’ve compensated Offset and Full-scale error.

Also what about DNL and INL errors do I want to consider both in my calculations and INL is the integral sum of DNL errors.

Also should I consider Typ or Max values what’s the difference between them?

Thank You in Advance
