What 's the difference of mark "Z" of EVAL-AD5380EBZ?

Question

Dear Sir/Madam, 
 I bought your EVAL-AD5380EBZ. 
 Can I use your document EVAL-AD5380EB's (without Z) from following URL? 
 http://www.analog.com/static/imported-files/eval_boards/602616229AD5380_1_2_3EB_0.pdf 
 Above document for without Z model. Not with Z. 
 With Z: Is this model for RoHS? 
 Please confirm this. 
 Thanks Kaos

You are correct, the Z indicates that all the components are lead-free and the board is RoHS compliant. The document you referred to is from an older version of the evaluation board. I have attached the newest version. This is also included in the evaluation software install file.
