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. An 8 MHz crystal is used as the external clock source. The AHB prescaler is used to reduce the frequency
when f
HCLK
< 8 MHz, the PLL is used when f
