nRF52832 temperature sensor accuracy

[PVS]

Hello:

The product specification (v1.3, pg 263) says temperature sensor accuracy min = -5 C and max = +5 C.

Its not clear if these accuracy values correspond to the temperature sensor range (min = -40, max = 85 C), and should be read as "accuracy = -5 C at -40 C" & "accuracy = +5 at 85 C". (And shouldn't accuracy be +/- ?)

What accuracy can be expected (say) between 5-15 C, with and without manual (offset) calibration?

Thanks

No, the accuracy is ±5°C over the whole temperature range, with ±2.5°C at the 25°C temperature point.

The 5-15°C range is not expected to stay in the ±2.5°C limits, so only the ±5°C limits apply here - YMMV.

Note that this is the die temperature, which could be several degrees over ambient due to heat generated within the package.
