order free samples

Hello!

Please help me!

I want to order DAC902E free samples, but it didn't work. The following was prompted to me:

You are only allowed to order up to 0 silicon line items per order, you have 1. Please remove the highlighted devices, or, purchase these parts in order to checkout.

please use enterprise email domain name to apply samples

I use university email address to apply samples. I am not sure whether this is allowed.

University email should be fine. 

DAC902 is a high speed DAC, migh have some limition to university email.

Please try to apply OPA171 for testing whether your email can be used for sample apply
