What is the temperature sensing accuracy of the LPS22HH for less than 0C?

Hello, according to the datasheet for the LPS22HH, in Table 3 the temperature sensor operating range is -40C to +85C. Further down, it specifies that the temperature sensor absolute accuracy is +/- 1.5C from 0C to 80C.

What is the accuracy from -40C to 0C?

Thanks,

Derek

    Hi Derek @smithderek2000​ ,

    below 0°C the accuracy is a little worse, probabily because it is more difficult to test in a humidity controlled environment, but nevertheless it is inside +-2.5°C (data from bench measures on representative samples), and almost across all the declared pressure range.
