Operational Amplifiers (Op Amps) are in stock with same-day shipping at Mouser from industry leading manufacturers. Mouser is an authorized distributor for many op amp manufacturers including Apex Microtechnology, Microchip, STMicroelectronics, Texas Instruments & more.

Operational amplifiers (op amps) are high-gain analog integrated circuits designed to amplify, condition, filter, and process electrical signals within electronic systems. They provide versatile signal manipulation capabilities through external feedback networks, enabling precise control of amplification, comparison, filtering, and mathematical operations. These devices serve as fundamental building blocks in analog circuit design, supporting a wide range of measurement, control, communication, and signal processing applications.

Types: The most common operational amplifier types include general-purpose op amps, precision op amps, low-noise op amps, high-speed op amps, rail-to-rail op amps, low-power op amps, chopper-stabilized op amps, and programmable operational amplifiers, each optimized for specific performance, accuracy, and power requirements.

Applications: Operational amplifiers are widely used in industrial automation systems, medical devices, test and measurement equipment, sensor interfaces, audio systems, communication equipment, power management circuits, and embedded electronics for signal amplification, filtering, conditioning, and control functions.

Selection requirements: To choose operational amplifiers, evaluate bandwidth, slew rate, offset voltage, input bias current, noise performance, supply voltage range, power consumption, output drive capability, package type, and suitability for the intended electrical and environmental conditions.
