DTS, DIGITAL TEMPERATURE SENSOR ON STM32H562

[liraz_abramovsky]

hi, I wanted to ask,
I saw that the micro STM32H562 datasheet has a new DTS digital temperature sensor. 
I wanted to ask :

1.what is linearity of this sensor?

2.what is its max error?

3.what is the level of accuracy?

I see that it is new so I wanted to check if it is worthwhile and safe to use it already?

thank you, 

Liraz Abramovsky.

Welcome @liraz_abramovsky, to the community!

You will find the description of the DTS in section 3.25 of the STM32H562 data sheet:

Digital temperature sensor (DTS)
The devices embeds a sensor that converts the temperature into a square wave, whose frequency is proportional to the temperature. The PCLK or the LSE clock can be used as reference clock for the measurements. Use the formula given in the product reference manual to calculate the temperature according to the measured frequency stored in the DTS_DR register.

and in Table 102 the parameters you asked about.

Hope that helps?

Regards
