D/A converter ISL5729/2IN component marking questions

Question

I have some Intersil ISL5729/2IN components I am trying to decode the part marking , Lot Date Code and Assembly site, 
 
 The marking on the component is as follows: 
 
 "I logo" 
 ISL5729 
 /2IN 
 P731BT5 
 Does anybody know how to decode the P731BT5 code?

I understand, I have been working this issue for several weeks. and I am familiar with the issues of procuring components outside of the OEM authorized distribution network. I also understand OEM reluctance to assist in any broker part authentication activities. My company does not purchase broker parts, however we have 3rd tier suppliers that do. I also know that Intersil is a fan favorite supplier for counterfeiters due to the unique nature of the products and lack of interchangeability. There is a paper written by Yong Hong in the 2011 ISTFA proceedings I think you would be very interested in.
