Integrated Cross Point Switches activate the input selected by the user. In single channel mode, one of the four inputs can be selected as valid input to the single ADC channel. In dual channel mode, any two of the four inputs can be selected to each ADC channel. In quad channel mode, any input can be assigned to any ADC channel. An int...
