How can I fix this 4-20 mA current loop to source current that matches current sink on its input? Building on a previous question about terminology, I am trying to arrive at a solution to connect a digital air pressure regulator that sinks current as part of its 4-20 mA current feedback loop to an ADC that also sinks current. Block Diagram: Block Diagram The pressure regulator has two ... (more) |

Is a current-dependent current source and a current mirror the same thing? I have a 4-20 mA digital air pressure regulator which is controlled by and reports its pressure by being the current sink in two independent 4-20 mA current loops. Our control system utilizes Analog Devices AD4111 ADC which itself sinks current. I've ran into numerous roadblocks in trying to de... (more) |
