Datasheet of TMP102 shows typical error 0.5C (max 2.0C) between range -25~+85C. Is it possible to get +/-0.2 error between range +25~+45C range through calibration? Any advice is appreciated. TMP112 has better performance, but it is more expensive.
I will get back to you on this topic tomorrow.

+/- 0.5°C is the best accuracy you can obtain with TMP102. Calibration is possible on TMP112 not TMP102. TMP112 comes precalibrated for 0.5C accuracy and can be calibrated to get less than 0.2C.
Can you please share more information about your application?
Thanks. Could you please introduce why TMP102 can't be calibrated? We can talk through mail if necessary.
The application is to measure the body surface temperature. A metal path will transfer the thermal charactor from body surface to sensor GND plane.

We are facing the same problem as mentioned above.Can i know the reason why we can't calibrate using TMP102. Here we want an accuracy of +-0.5°C. But as per your data we are getting 2°C deviation. Here our area of interest is in between 0°C to 10°C. If you want you can even mail me on email@example.com

First of all I would like to bring to your attention our next generation temperature sensors that have higher accuracy spec: TMP112 as you may already be aware of, and TMP107 which is going to be available by the end of this month. Both devices boast a guaranteed MAX temperature error spec of 0.5⁰C. You are certainly welcome to consider these devices for your application. As a matter of fact I think you can easily swap TMP112 for TMP102 in your system without HW and SW retooling.
In my opinion, any temperature sensor can be calibrated; it all depends on target accuracy and how much effort is budgeted for the calibration process itself. Another aspect to consider is whether each system will be calibrated individually or the calibration is done on a sampled basis. You can always create a look-up table to account for the offsets.
