1. Typical values are measures at TA = 25 °C, VDD = 3.3 V.
2. Add an additional power consumption of 0.8 mA for the ADC and of 0.5 mA for the DAC analog part. In
applications, this consumption occurs only while the ADC is on (ADON bit is set in the ADC_CR2 register).
3. AHB prescaler used to reduce the frequency (when fHCLK > 8 MHz).
