Questions & Step-by-Step Solutions
Which application commonly uses an operational amplifier?
Step 1: Understand what an operational amplifier (op-amp) is. It is an electronic component that can amplify voltage signals.
Step 2: Learn about the voltage follower application. A voltage follower is a specific way to use an op-amp.
Step 3: Know the benefits of a voltage follower. It has high input impedance, meaning it doesn't draw much current from the source, and low output impedance, meaning it can drive loads easily.
Step 4: Recognize that voltage followers are commonly used in circuits where signal integrity is important, such as in buffering signals.
