Abstract
A multiplexing circuit uses parallel-configured switch/resistor pairs in a voltage divider network in such a way that a single analog-to-digital input can be used to specify the state of more than one switch or other component. One circuit includes a reference voltage node, a ground node, and an output node, wherein a switched voltage divider network is configured such that the voltage at the output node is unique for every given combination of switch states.
