Schematic

Open project folder on GitHub

Demonstrates an op-amp summing (adding) amplifier.

Circuit Summary

Multiple input resistors feed the inverting node, producing a weighted sum at the output.

Expected Behavior

  • Output equals the scaled sum of input signals.

How To Run

  1. Open OPamp-adding.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

  • Vary input resistor ratios to change weighting.
