Common Amux Connections
I am trying to connect a common from an 8 to 1 mux to an input to a 2 to 1 mux. These are just software analog muxes. I am trying to route from external pins to an ADC, switching routes between direct to ADC or through a TIA. I have attached a picture of the schematic. Currently, I have a buffer the direct to ADC line, but I would like to get rid of that if I could. Do I need a buffer between an external pin and ADC?
