what is "independent clock domain" STM32l412

Ach.1 · ‎2020-05-13

Hi all.

i using the ADC in STM32L412 MCU .

according to the DS , the current consumption of the ADC in Range 2 is 0.2uA/MHz for independent clock domain and 1.8uA/MHz for clock domain...

what is the "independent clock domain"

according to the DS , the ADC can run only at SYSCLK ( Figure 4. Clock tree )

I'd say, a copy/paste artefact from other 'L4 datasheets.

It decreases the credibility of the given value, though.

@Amel NASRI , can you please have a look at this?

Thanks,

JW

Btw.

which is probably bogus, too.

thanks @Amel NASRI & @Community member .

can you kindly also answer my other Q "STM32L4 ADC power consumption VS ADC FREQ"

that i didn't got no comment.

thanks.
