Original question:

TMP116: NIST traceable calibration certificates are kept on file at TI

TMP116: Nist traceability and Unique ID ?

Robert Jan Gorter

Part Number: TMP116

The TMP116 datasheet states that a unique ID is stored in the EEPROM to support NIST traceability. 

Does this imply that we can also receive the individual validation/calibration measurements of each individual device based on the stored unique ID in the TMP116 EEPROM ? How does that work and how does that info looks like exactly.  Can you share that information and indicate how and under which conditions we can receive this information that is coupled to the unique ID that is stored in the EEPROM ?

    Hi Robert,

    The ID allows us to link the devices to their individual production test records, but this record is not available to the public. We're not able to issue individual certificates the way it is done for other sensing technology. Our datasheet guarantees that all devices shipped meet the min/max accuracy described in 6.5 Electrical Characteristics table. 

    On the TMP116 product page, you can retrieve a statement from TI regarding NIST traceability by clicking the Request now button. 

    thanks,

    Thanks. I used the request button. Out of curiosity, can you tell us what information is retained using the unique ID?

    Hi Robert,

    The unique ID enables us to link a device to its individual production test record. Without the ID, our normal device markings can only identify final production lot. The ID includes wafer ID, device location in the wafer, and similar information that isn't useful without matching it to our production test records. There is no path within TI to offer production test record, even of very small scope, to the public. We are able to audit our process as needed, but it currently isn't feasible to offer it to customers.

    thanks,
