This is the analog front end for a 3-bit flash ADC, perhaps the simplest implementation of an analog to digital converter.
Following this analog circuit would be a digital decoder to go from the comparator outputs to a 3-bit binary number..
You can use this circuit also for a voltage measurement. The result you can see at aLED-strip.
My favorite resource for learning more about flash ADCs is the Maxim Integrated app note:
