i am doing some ratiometric resistance measurements with the ADUCM360. Therefore I 'm using the excitation current source and both ADC's of the Chip.
To avoid errors due to thermoelectric effects, I want to rotate the current source. Therefore I would have to switch the GND connections of my voltage Divider.
My question is if there is a way to connect two input channels of the MUX, like ADC0 and ADC1 to the negative input of the ADC?
I don't clearly understand your question. Do you want to connect the ADC0 and ADC1 input channel to ADC at same time? If my guess is right, the answer is no. Only one input channel can be selected as the negative input of the ADC at the same time.
