interface an external high precision low noise delta-sigma ADC with Arduino

Seems like we have another member who prefers a grievance to a solution.

How about posting a link to the datasheet for the device you want help with with.

Also, I assume from the tone of your responses that you are not a newbie and that you will already have written some code to try to work with the device. Post the program that represents your best attempt and tell us exactly what it does and what you want it to do that is different.
