Operational amplifiers (op-amps) are not a specific brand but a category of electronic components widely used in analog circuits for amplification, filtering, and signal conditioning. They are produced by numerous companies globally, including Texas Instruments (USA), Analog Devices (USA), STMicroelectronics (Switzerland/France), and Infineon Technologies (Germany). These devices serve industries such as automotive, telecommunications, industrial automation, and consumer electronics. Key products include general-purpose op-amps, precision op-amps, and high-speed op-amps, available through distributors like Radwell and Grainger.
