Question & Answer
Choose the Best Answer
Determine the required gain for your application
Select an appropriate op-amp that meets the gain specification
Implement negative feedback to stabilize the gain
Measure the output to verify that it meets the design criteria
Understanding the Answer
Let's break down why this is correct
The first step is to decide what gain is needed for the application. Other options are incorrect because Picking an op‑amp before knowing the target gain is a common mistake; Designing negative feedback before selecting the op‑amp ignores the op‑amp’s stability limits.

Definition
While op-amps do not have infinite gain in practice, their high gain allows for reliable circuit design using negative feedback. Op-amp gain specifications vary between models, and practical op-amp circuits rely on predictable gain behavior.
