Adc_channel_vrefint
WebThis internal voltage is connected to ADC_IN17 (channel 17) and can be measured. Moreover, the precise voltage of VREFINT is individually measured for each part by ST during the production test and stored in the system memory area with respect to supply voltage Vdd = 3.3V. WebThis assumes vrefint is a known value, and while there is a typical value for it in the datasheet and we can use it as it is, for increased precision, we want to know its voltage as precisely as ... ADC input channels in the ADC MUX. This sensor outputs a voltage which is fairly linearly proportional to the internal temperature of the chip (i.e ...
