Hello ,
I need help in creating a controllable current source using DAQ(PXI-1042). The current range needed is around 0mA to 400mA. Now the current from the DAQ AO pin is very low; around 10mA. How to I get a controllable current of my range? I am trying to use LM317 regulator, but I am not sure about the pin connections. I have attached my circuit diagram here; but that is not working. Can someone please suggest me where am I going wrong? How should i connect the LM317 pins and if there is any other method to get a adjustable and controllable current output? Thanks in advance.
