14.4V ground reference for ADC

<< < (7/33) > >>

If i do that I can get rid of that 1 \$\Omega\$ and go to milliohms. ;D

He wants to drop up to 1V on the shunt resistor, 1.5V on 18V does not require too much of a loss in that range. The circuit he has posted already has a current shunt amplifier. To be honest i am confused as to what he is trying to do here.

Yes you are right I am over complicating everything myself |O.I will measure the output of the current sense  amp using ADC so i can get rid of that GND REF.If i do that i can  use shunt with lower resistance.So higher efficiency :D :-+.

Yes i need to start on something simpler.But I decided to built this because i don't have a PSU and i needed one and i thought  i can  build one myself.Yes there are cheaper PSU s than my whole project costs and with more power(mine is only 18W) but they don't have that much precision.

Arjunan M R:
Here is the full schematic.Note that i recently changed the MCU and didn't connect all the connections.
I have made some changes now.Written on black is net labels.

Here is the image of the full schematic.
