Part Number: ADC141S628-Q1

I would like to understand the difference between total unadjusted error (TUE) and effective number of bits (ENOB). I am doing a worst case analysis from -40c to 105c and need to know if I should use TUE values or ENOB values to evaluate the true number of bits that this A/D will provide.

Hello,

We have couple of blogs that cover this topic.

The first I would suggest to read is the ADC Accuracy: Is accuracy different from Resolution, it is a three part blog and will prove to be very helpful.

This three piece blog will cover your question and explain how and when to implement each.

There is also another fun three part blog about ENOB, if you would like to read more about the topic

And then there was noise: the mystery of the missing ENOB

Regards

Cynthia
