What is the maximum error of this ADC?

I've read every article on the first two pages of Google trying to understand DNL and INL. Not a single lesson gave a specific example I could relate to, so now I'm still wildly confused and have no idea how to calculate this value. I'm thinking…

How to minimize the effect on DNL error from this opamp circuit?

By using the following single LM324 circuit, I create amplified bipolar outputs from a 16-bit 0-3.3V DAC output as follows: My aim is to minimize extra DC error due to the above LM324 circuit especially not to increase the DNL at the final output.…

Number of data points needed for INL DNL estimation

In this article where ADC of pico pi is characterized, I found a part that I have never encountered in my study of mixed signals design: I don't understand how we number of data points needed is derived and how it is related to N and DNL…

A question about interpreting DNL

Imagine a 12-bit DAC with a range 0.2V to 3.4V and its DNL spec given as ±2 LSB. I want to increase this DAC in stair step fashion(as shown in below illustration) from 0.2V to around 3.2V with around 3mV step increases in total number of 1024…
