Hi,
I'm not quite sure if the current consumtion while powering the ADM3251E at 3.3V is just = 2.5 + 12 + 6.2 = 20.7 mA like the datasheet seems to display. The concerns comes from comparing it to the consumption when it is powered up with 5V. I know the internal DC-DC is not enbled on the fist case but still, it's such a big difference in consumption comparing powering it up with 5V or with 3.3V.
Can some one please give me a hint?
Thank you very much.
