LM393 Voltage Comparator Circuits
The comparator component has 2 inputs that monitor the voltage delivered to them. One input is called the – (inverting) input, and the other is called the + (non inverting) input.
- Noninverting input voltage > Inverting voltage = High output
- Noninverting input voltage < Inverting input = Low output
The comparator’s output goes high (close to the rail + voltage) when the non inverting input (+) is at a higher voltage than the inverting (-) input. Whereas, the comparator’s output goes low (close to the rails – voltage), when the non inverting (+) input has a lower voltage than the non inverting input (-).
