Hi
Can you please advise if the temp. sensor reading is for the device junction temperature or other part within the die?
Thanks

Temperature sensor is located near the die edge/corner adjacent to the DACs.

Could you please provide formula that converts from the temperature sensor reading to the junction temperature?
The temperature sensor outputs the temperature data in 8-bit, 2's complement format.
For example, 0 degree corresponds to b0000-0000, 25 degree corresponds to b0001-1001. The MSB indicates the positive or negative sign. For instance, -2 is represented by b1111- 1110.
To calculate the negative temperatures, first calculate the values as you would for any binary to decimal conversion, and then subtract the decimal from 2^8 or 256 (i.e. b1111-1110 = d254. 254-256 = -2 degrees).
If you have more questions, please feel free to let us know.
Hi
I'm familiar with the formula that you mentioned. What I don't know is how convert the temperature sensor reading to the device's junction temperature.
Hi,
The temp sensor is on the chip (die) itself, so it is reading the temperature of the die.
We don't have the details of your question since we do not have the designs.
