Engineering What is the impact of ADC quanta on op-amp offset error?

[electronic engineer]

Homework Statement

op-amp with 10-bit ADC

Relevant Equations

V(o)=-V(io)*(1+R2/R1)

Hello,

i have questions from a book that I'm reading, it's full of interesting problems about Electrical Engineering. For now i want to ask about op-amp offset error.

I will post a copy of the problem here.

We can talk about it, i have an idea about offset error so i can share it here later, but for now can you just tell me about ADC quanta?

Thank you.

You've been a member of PF long enough to know that's not how things work here. Please show us your work and links to the reading you've been doing about this subject, so we can help you find any errors or misunderstandings in your work.

Also, what do you mean about "ADC quanta"? Are you asking about various measures of ADC quantization error, or something else? Again, it would help so much to see links to your reading on the subject, instead of having to guess what you are asking about.

Thanks.

It is a waste of your time and ours to post images that aren't readable.

Agreed. @electronic engineer -- Please check your PMs and start a new thread with the improvements I suggested. Thank you. This thread is closed.
