Stm32 vrefint

STM32 peripherals like ADC or OPAMP may embed a self-calibration circuitry but some others like internal oscillators or VREFBUF require a measured trimming performed during factory. A specific parameter (output voltage for VREFBUF case) is adjusted by trimming, based on a register word value..

STM32F334 peripherals interconnect matrix. 7.3 Interconnection details. Table 23. DAC output selection as comparator inverting input. 7.3.12 From VREFINT to COMP. Other observations: Although the STM32 ADCs have an internal voltage reference and even store their values measured at the factory at 30°C and 3.3V - you can only use that for calibrating. You can measure the actual VRefInt value and calculate your supply voltage based upon that. Which is in case of STM32F030P4 always your ADC reference .... Using the internal reference voltage of the ADC. I am using an STM32L432KC (on a NUCLEO-32 board) in my project and I need to monitor the battery voltage, which I am doing by.
