Key Terms

Operational Amplifier
A high-gain voltage amplifier with differential inputs and a single output.

Example: Op amps are used in various applications like filters and amplifiers.

Saturation
The condition when an op amp output reaches its maximum or minimum voltage limit.

Example: An op amp saturates when the input signal exceeds the linear range.

Feedback
The process of routing a portion of the output back to the input to control the gain.

Example: Negative feedback stabilizes the gain of an op amp circuit.

Clipping
The distortion that occurs when an amplifier is driven beyond its limits.

Example: Clipping can occur in audio amplifiers when the input signal is too strong.

Linear Region
The range of input voltages where the output of the op amp is proportional to the input.

Example: An op amp operates in the linear region when it is not saturated.

Power Supply
The source of electrical power for the op amp, determining its output limits.

Example: A dual power supply allows an op amp to output both positive and negative voltages.
