In my design I'm feeding a differential analog mux into a differential ADC. I want the reference voltage for each to be the same, which should be a pin on my board. In the ADC I have vref set to the pin I want, but when I also try to wire a pin to each of the secondary inputs on the mux I get errors. How can I have the same Vref for both the ADC and the mux? I've inluded a picture of the design.

Thank you

You need to make this connection externally. PSoC Creator doesn't allow you to bind an analog pin to a pin which is used for another component (the DelSigADCs Vref in this case). So bind the common mux input to a separate pin, and connect it to P0[3] (ot P3[2], depending on what is set as Vref input) with an external wire. On the -050 kit, all pins of port 0 and 3 are available on the prototyping area, so this should be easy.

Hi  MattCoughlin,

- What error are you getting ? Can you attach error message ? 

- The picture you attached, pin numbers are not visible. Can you mention pin numbers or attach a clearer picture ?

 I just soldered another pin to the one I was using, and it seems to be working now.
