What type of OpAmp configuration is described as inverting?

An inverting OpAmp configuration is characterized by how it processes the input signal. In this configuration, the input signal is applied to the inverting terminal of the operational amplifier, leading to a phase inversion of the output signal relative to the input. This means that if a positive voltage is input, the output will be negative, and vice versa.

In the inverting configuration, a feedback resistor is connected from the output to the inverting terminal, while the other terminal of the input signal is grounded. As a result, the OpAmp amplifies the input signal while maintaining its phase inversion, which can also be quantitatively expressed with the gain formula, where the gain is determined by the ratio of the feedback resistor to the input resistor.

The description of inverting behavior aligns perfectly with the characteristics of analog inverting configurations, making it the correct choice. The options related to non-inverting configurations and digital modes are fundamentally different in terms of signal processing, which is why they are not applicable in this context.
