Can I connect the VxGND to a constant voltage reference of +5V and connect Vx to a signal of 0~10V? Accordingly, I need to set the ADC range at +/-5V.
Although AD7606 is not a truly differential input ADC and the datasheet mentioned that VxGND should be connected to the AGND plane, the figure 34 of the datasheet seems fine with this pseudo differential input connection. Can one of your engineers confirm whether this is OK or not and what's the possible performance loss if I do it in this way? Thanks.
