Analog-to-digital converter (ADC) RM0033
236/1381 RM0033 Rev 9
Figure 46. Case of trigger occurring during injected conversion
10.10 Temperature sensor
The temperature sensor can be used to measure the junction temperature (T
J
) of the
device.
The temperature sensor is internally connected to the ADC1_IN16 input channel which is
used to convert the sensor’s output voltage to a digital value.
Figure 47 shows the block diagram of the temperature sensor.
When not in use, the sensor can be put in power down mode.
Note: The TSVREFE bit must be set to enable the conversion of both internal channels:
ADC1_IN16 (temperature sensor) and ADC1_IN17 (V
REFINT
).
Main features
• Supported temperature range: –40 to 125 °C
• Precision: ±1.5 °C
