Schematic

Open project folder on GitHub

Demonstrates an op-amp used as a comparator.

Circuit Summary

The op-amp compares an input signal against a reference threshold.

Expected Behavior

  • Output saturates high/low as the input crosses the threshold.

How To Run

  1. Open OPamp-comparator.kicad_sch in KiCad.
  2. Click Simulate and run the configured analyses.
  3. Add probes to the key nodes to view the expected behavior.

Notes

  • Add hysteresis if you want cleaner switching.
