What role do operational amplifiers (op-amps) serve in electronics?

Operational amplifiers (op-amps) play a crucial role in electronics primarily by performing signal amplification and facilitating various mathematical operations. As versatile components, they can amplify weak electrical signals to more manageable levels, making them suitable for processing in various circuits. This amplification is essential in many applications where signals from sensors or other devices must be boosted to be effectively used or measured.

In addition to amplification, op-amps can perform mathematical operations such as addition, subtraction, integration, and differentiation. This makes them invaluable in analog computation tasks, allowing for the implementation of complex functions in a straightforward manner. By configuring op-amps in certain ways, engineers can create circuits like summing amplifiers and integrators, showcasing the component's ability to manipulate signals mathematically.

While signal filtering and data conversion are relevant functions in electronic systems, they do not capture the full scope of what op-amps do. Power generation and storage, as well as electrical insulation and protection, are functions typically associated with other components, so they don’t accurately represent the primary roles of operational amplifiers.
