AD74413R ADC ERROR

Hi,

Kindly share the Offset drift,gain drift, PSRR of AD74413R for analog input and voltage input

Also please let me know by using internal and external reference how rthe accuracy got effected?

Warm regards,

    Hi, 

    Again, The datasheet provide the info that you need. Please refer to the specs section. Looks like the TUE is already tested for this part and that gives you the overall ADC error at 25C and across temp. And I believe the TUE is tested using the external reference so if an internal reference will be use then you have to consider the internal reference error. 

    I'll pass you with the product owner to better assist. But I guess, as I am suggesting to the other user it would be easy to take this offline with our local FAE. You can explain all of your system application and put all of your questions on a single request and the FAE can comeback to you with a complete answer across all of the related products. 

    Thanks,
