Hello,
I have a question. I have been trying using a DS1867 digital potentiometer in a circuit that will replace a mechanical potentiometer of 250KOhm. The circuit/device that is uses the pot is an AC voltage controller made by Radio Shack (cat 64-2054). When I substitute the DS1867 digipot for the standard pot, the load is not powered.
What might the problem be? I've now fried two of these Rad Shack voltage controllers in attempt to test a digitally controlled pot. I don't think the digipot was damaged. Is there another passive component required in the circuit (cap or resistor) that needs to be added?
Thanks Mike
