Temperature sensor

The temperature sensor can be used to measure the ambient temperature (T
device.
The temperature sensor is internally connected to the ADCx_IN16 input channel which is
used to convert the sensor output voltage into a digital value. The recommended sampling
time for the temperature sensor is 17.1 µs.
The block diagram of the temperature sensor is shown in
When not in use, this sensor can be put in power down mode.
Note: The TSVREFE bit must be set to enable both internal channels: ADCx_IN16 (temperature
sensor) and ADCx_IN17 (V
