Please check this thread for possible solution using current mirror
Another method can be using PSoC opamp in Howland pump configuration +IDAC. Not sure it will hold 20mA. See Figure 13 in
Hi,i want to create 4-20mA output on psoc5.how can i do that?
another one can i change output voltage control with fixed current that created on idac ?
Thanks, I will try it later,
just I know now that is a solution in my request.
Thank you very much for help.

thanks a lot for answer but i want to creat a 4-20mA source with IDAC.i want to control an electrical switch with IDAC.(electrical switch has a controller between 4-20mA for speed and some function).
thanks a lot...
No body can help me?I need 4-20mA source to control some device.how can i do that with psoc5?
What is the load resistance?
load is 125 ohm.is it ok?or not?
