Power op amps, or power operational amplifiers, are not a specific brand but a category of high-performance amplifiers designed to deliver significant output power for industrial and electronic applications. These components are produced by various global companies, such as Texas Instruments (USA), Analog Devices (USA), STMicroelectronics (Switzerland), and Infineon Technologies (Germany). Power op amps are widely used in industries like automation, motor control, audio systems, and power supply management. Key products include high-current op amps, rail-to-rail output amplifiers, and precision amplifiers, which ensure efficient signal processing and power delivery in demanding environments.
