Operational Amplifiers (Op Amps) are pivotal in electronics, amplifying voltage differences between inputs. Gain, the output-to-input voltage ratio, is crucial for applications like signal conditioning and analog computation. Gain is influenced by feedback, frequency, and temperature, and varies with configurations such as inverting, non-inverting, and unity gain. Understanding gain is key for designing circuits with optimal performance.
