Question: 1 / 400

What is the key characteristic of an inverting amplifier?

Input supplied to POSITIVE

Maintains constant phase

Uses a positive feedback loop

Input supplied to NEGATIVE

An inverting amplifier is characterized primarily by its configuration in which the input signal is supplied to the negative terminal of the operational amplifier. This arrangement makes it possible for the amplifier to produce an output that is inverted in phase relative to the input. As a result, when the input voltage increases, the output voltage decreases, and vice versa. The key concept here is that the active behavior of the inverting amplifier depends on the input being directed to the negative input terminal, which facilitates the phase inversion.

While the other options describe characteristics of amplifiers more generally or pertain to different configurations, the defining feature for inverting amplifiers specifically focuses on the negative terminal connection, leading to the inverting behavior they are known for.
