Operational Amplifier/Comparator

Operational amplifiers (op-amps) and comparators are analog devices used for signal amplification and comparison in electronic circuits. Op-amps amplify weak signals, providing high gain and stability, while comparators compare two input voltages and produce a digital output indicating which is higher. These components are widely used in signal processing, control systems, and instrumentation. Their versatility and precision make them fundamental building blocks in analog circuit design.
