Top Marking not matched in datasheet

Question

Hi, 
 Good day. 
 My customer feedback that they received the parts (PN# MAX1792EUA25/V+) with top marking "AACR" which not tally with the information stated in datasheet. 
 https://www.analog.com/media/en/technical-documentation/data-sheets/max1792.pdf 
 According to the datasheet, the correct top marking should be "AAAB" but not "AACR". 
 Can you please help to review and advise if my customer received correct parts or not? 
 If correct, is it possible to share the datasheet with correct top marking information? 
 Thanks.
