I came across a paper, written by Chris Glaser, regarding "Harnessing wasted engergy in a 4- to 20-mA current-loop systems"
I was wondering if you could give me a little help.
I am trying to use the system as you describe in the document in figure 2. Can you shed light on how to connect the supply as shown in the diagram, while keeping the current loop intact.
I'm using a TPS62125EVM as the power supply, a XTR111-2EVM as my transmitter, a 165 ohm receiver resistor with the INA138 level shifter.
Do you have a sample schematic, or reference design that I could reference. How do you connect the TPS62125 to work as power supply, while maintaining the current loop?
Thanks is advance to any light you can shed on this.
