Abstract
A circuit includes analog input nodes and switches selectively coupling each of the analog input nodes to a capacitive node. Each of the switches is controlled by a respective bit of a channel selection word. Level shifting circuits are respectively coupled in parallel with the switches. A sampling capacitor is coupled between an output node and ground, the output node being coupled to the capacitive node. An analog to digital converter operates to digitize voltages at the output node.
