Hello
Can you help me know what is 14XX means? in the sensor LM35CZ/NOPB
Best regards!
Hi Aisha,
The first two digits refer to year month date code. According to our assembly build procedure, there should be 3 digits after the date code that refer to the assembly lot code. There seems to be a discrepancy with these units. Do you have the LTC information from the packing reel?
Best regards,

Hello, let me check and I'll send it to you,
We also want to know were is indicate the useful life of the sensor?
Best regards!
Aisha,
This will ultimately depend on the average use temperature of your application. The device is spec'd for a long term drift as seen below at 150C for 1000 hours.
This spec is achieved by testing the device's accuracy before and after an accelerated life stress test. If you share the expected average application temp, I can tell you how many hours/years of use the stress would be equivalent to.
Best regards,
Simon Rojas

Hi Aisha,
Thanks for the info, I will forward this to our product team to verify whether the lot trace codes align with the information you provided. I will have an update for you by tomorrow.

Hi Aisha,
Thank you for your patience, I just heard back from our product team. It appears that this date code points to a build in 2011 which makes these devices fall outside of TI standards when it comes to the backside marking. As mentioned before, builds within TI standard will have 5 digits as follows: YMLLL--Year (1 digit), Month (1 digit), Lot trace code (3 digits).
