External Vref on Mux
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.
