Interrupts: end of conversion, overrun, analog watchdog, short circuit, input serial

channel clock absence

•

“regular” or “injected” conversions:

–

“regular” conversions can be requested at any time or even in continuous mode

without having any impact on the timing of “injected” conversions

–

“injected” conversions for precise timing and with high conversion priority

Temperature sensor

The temperature sensor has to generate a voltage that varies linearly with the temperature.

The conversion range is between 1.7 V and 3.6 V. The temperature sensor is internally

connected to the same input channel as VBAT, ADC1_IN18, which is used to convert the

sensor output voltage into a digital value. When the temperature sensor and VBAT

conversion are enabled at the same time, only VBAT conversion is performed.

As the offset of the temperature sensor varies from chip to chip due to process variation, the

internal temperature sensor is mainly suitable for applications that detect temperature

changes instead of absolute temperatures. If an accurate temperature reading is needed,

then an external temperature sensor part should be used.
