HDC2021: Comparison of temperature read by HDC2080 and HDC2021

Part Number: HDC2021
Other Parts Discussed in Thread: HDC2080,

Dear Team,

We are using the temperature and humidity sensors from TI in one of our design. We have produced 50 boards with HDC2021 and 50 with HDC2080. We have observed that the boards with HDC2080 are reading on an average 0.8°C higher than HDC2021. Can we know what are the reasons for the difference in reading the temperature? However no difference is observed in Humidity reading. Below images give the details of the temperature read by 1 HDC2080 board and 1 HDC2021 board. This log was taken continuously for 4 hours in room temperature. Similar response was observed with other boards as well.

Kindly give us feedback and probable cause for the difference soon. It is important to adjust the offset in our sample accordingly
