1. Typical values are measures at TA = 25 °C, VDD = 3.3 V.
2. Add an additional power consumption of 0.8 mA per ADC for the analog part. In applications, this
consumption occurs only while the ADC is on (ADON bit is set in the ADC_CR2 register).
3. External clock is 8 MHz and PLL is on when fHCLK > 8 MHz.
