[QUOTE="Baluncore, post: 6524489, member: 447632"] A column of series resistors provide reference voltages spaced between Rhi and Rlo. Comparators check the input voltage Vin, against all the reference voltages. In one LED only mode, the digital outputs of adjacent comparators go to XOR gates that turn on the LED where the comparator outputs are different. Rather than a bar, that will show only one LED on.
