STMicroelectronics 

STM32L151x6/8/B, STM32L152x6/8/B

Electrical characteristics

6.3.5

4. Data based on a differential IDD measurement between DAC in reset configuration and continuous DAC

conversion of VDD/2. DAC is in buffered mode, output is left floating.

5. Including supply current of internal reference voltage.
