How IS it intended to work?
I would guess that 0V out from the DAC should correspond to 4mA and 3.3V should correspond to 20mA

VREG will be powered by external thru the Jack. There is no data being received or transmitted by DAC to the MCU.
I am wondering if I should power DAC independently from VREG?
