Hi group!, this is the first post I make, and I would be very glad if you orient me.
I am designing an analog I/O card with several step down DC-DC converters (basically to energize the signal conditioning circuitry), and at one moment I got confused with the amount of current I should be able to supply.
To sum up, I am not so sure which parameters I should look for in the datasheets of the chips, to get an estimation of the current that every single IC could consume at maximum. By knowing it, I would be able to design a converter able to provide the right amount of energy. I mean, if I am going to use one instrumentation amplifier, one comparator, etcetera, knowing the voltage required, which current should I supply to them at maximum?
I know this is a very basic question for the designers, but I am just a begginer in design (but in electronics theory).
Thank you in advance...
