I know that "AD9254" is a commercial grade ADC and "AD9254S" is a space grade ADC.
My question is, are the dies of AD9254 and AD9254S same or different?
This is a technical forum and we are here to help with technical questions on our products in customer applications. If you have lead time issues on products we can't help. I suggest you go back to your supplier or contact your local ADI sales contact.
May I ask why you are interested in the die on these products?
I am interested in the "AD9254S" (space grade) because I need the TID performance of "10 Krad".But it is diffiult to buy the space grade chip due to too long delivery.
Although the packages of space grade (AD9254S) and commercial grade (AD9254) chips are different, if the dies are same, I think the commerical grade chip has an advantage for achieving the TID performance of "10 Krad".So I asked the die types of these chips ("AD9254S", "AD9254").
Do you know some distrubuters with stock?
Can you recommend some methods to buy space grade chips with short delivery ?
