Op Amp Discovery

Fast & Flexible Prototyping & Experimenter Board

The Op Amp Discovery Board allows students, engineers and DIYers to quickly build and learn a variety of op amp configurations. Hands-on prototyping and experimenting boosts understanding and intuition!

• Easy-to-use hybrid (solderless breadboard + PCB).
• Explore 20+ classic op amp circuits
• Create your own circuits
• Supply Rails & Signal Source Included on-board

Fast & Flexible Prototyping

Quickly build and explore many classic op amp circuits with component headers and configurable circuits. Follow self-directed or guided learning.

• Flexible - easily install Rs, Cs or jumpers across any headers.
• Fun problem solving - How-to-build circuit on headers?
• Configurable signal - DC, AC, square-wave, level trimpot

Problems Solved

• Standard breadboards can be frustrating:
  • Prone to opens, shorts, intermittent connections
  • Confusing, difficult to probe and debug
  • Requires expensive, bulky supplies and signal generators
• Op Amp Discovery:
  • PCB provides solid, versatile connections, power and a signal source.
  • Layout arranged like schematic to reinforce learning.
  • Minimal cost and PCB space - an affordable & portable learn-anywhere lab.
  • Learning possible with a $10 DMM only.
