The output of an op amp wired as an inverting comparator will swing in the opposite direction of the signal whenever the signal crosses a reference voltage.
For an inverting op amp comparator circuit…
- Reference voltage is applied to non inverting input.
- Signal voltage is applied to the inverting input.
That means that…
- Output voltage is high when the signal voltage is lower than the reference voltage.
- Output voltage is low when when the signal voltage is higher than the reference voltage.
