Choose AnswerChoose the Best Answer

A

The output remains linear and distortion is minimized

B

The output saturates to the supply voltage, causing signal distortion

C

The output is completely turned off, eliminating distortion

D

The output reflects the input voltage accurately without distortion

Understanding the Answer

Let's break down why this is correct

When the input goes beyond the allowed range, the op‑amp can no longer produce a proportional output. Other options are incorrect because A linear output is only possible inside the op‑amp’s range; The op‑amp does not simply shut off.

Op-amps have output limitations due to the voltage range of their power supply. When the output voltage exceeds this range, the op-amp saturates and outputs the maximum or minimum voltage. Saturation can lead to signal clipping near the power supply rails.
