Introduction
Basic operational amplifier (op amp) circuits are covered to death elsewhere. What is commonly not discussed, however, is that real-world (industrial, rugged) op amp circuits are NOT the basic ones commonly shown everywhere.
Real-World Op Amp Circuit Considerations
Real-world considerations (for an op amp in an industrial / commercial product) include the following:
- Provisions to prevent op amp from oscillation.
- Provisions to include filtering on op am input.
- Provisions to balance op amp input impedances, especially when filtering is employed.
- Picking an appropriate op amp IC type for the project at hand.
- And many others.
