If the sampling time is less than the time required to fully charge the CADC through RADC + RAIN (ts < tc), the digital value converted by the ADC is less than the actual value. Figure 15. Analog signal source resistance effect STM32 VAIN RAIN AINX RADC 12-bit ADC CADC VSSA...

value will be 72MHz which lead to maximum AHB (System clock) at 144MHz. Since the sampling time is set to 3 cycles and the conversion time to 12bit data is 12 cycles, so the total conversion time is (12+3)/36= 0.41us(2.4Msps). The converted voltage is displayed on the STM32F...
