Hello-
I am designing a 4-20mA current generator with XTR111AIDGQT. Following is a schematic. The series resistor between DAC andXTR111 is 243 Ohms instead of 10K.
It seems the chip is pretty strieght forward but I do have some issues with it. The DAC is 12 bit so it can set output from 0V to 4V. When I input 0V I observe ~0mA at the poutput but when I switch input to 2 or 4V output switches to 2.15V max.
I will appreciate your responses.
Regards
