1. Guaranteed by characterization, not tested in production unless otherwise specified.

2. Add an additional power consumption of 1.6 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. When the ADC is ON (ADON bit set in the ADC_CR2 register), add an additional power consumption of 1.6 mA for the

analog part.

4. Same current consumption for fHCLK at 30 MHz and 20 MHz due to VCO running slower at 30 MHz.
