I'm using an Arduino Due (3.3V) which has a maximum current for all pins 130mA.
How to estimate consumption for a number of ICs?
For an example i use multiple MCP4822 (2channel DAC)
On the datasheet I read "input current" 415-750 μΑ.
But what current the SPI clock signal and the MISO signal consume?
If i connect several ICs does this drains more current?
Does this DAC consumes so small current that i connect as many as i like?
EDIT: or please only a general guidance: how many ic in general (op-amps, digital pots, transistors) to stay below < 130mA?
About ten or about fifty?
