Thread Summary

                The user inquired about the difference in markings for 25 years and 24 years on unspecified parts. The final answer advised that Analog Devices does not provide information on part markings and suggested contacting the point of purchase for details. ADI only supports products bought through authorized distributors and sales offices.

   Could you please clarify? The markings for 25 years and 24 years are different. May I ask what the original marking represents?
