Hi,

i plan to build arduino controlled current source using the attached schematic ,the question is ,can i use Lf 347N instead of lm324? the second question ,what if i replace the the mosfet
with IRFZ44N and use only 4 instead of 6 ,the maximum voltage to be used is 14V and MAX current is 40A with large heatsink.

It looks OK, but I think 3 MOSFETs would work just fine depending on the heat sinking. You may have problems with A5 when the current sink has no load.
