HDC2080: Temperature Accuracy

Carlo

Part Number: HDC2080

Hi E2E,

Good day.

According to the HDC2080 datasheet, the temperature accuracy is typically +/-0.2 °C to +/-0.4°C, however, the test condition is at 5°C < TA < 60°C. The temperature sensor has an operating range from -40°C to 125°C, I would like to confirm if the temperature accuracy is true from -40°C to 5°C? and for the entire operating temperature range?

Regards,
Carlo

Dear Carlo -

Thanks for the question. Figure 3 of the datasheet http://www.ti.com/lit/ds/symlink/hdc2080.pdf (page 6) has the accuracy over temp over entire operating range.

from -40 to 5C the typical accuracy slopes down from ~ +/- 0.525 to ~+/- 0.225
