Fully differential amplifiers are a category of high-performance amplifiers used in precision signal processing, not a specific brand. They are widely utilized in industries such as telecommunications, medical equipment, and industrial automation. Leading manufacturers of fully differential amplifiers include Texas Instruments (USA), Analog Devices (USA), and STMicroelectronics (Switzerland). These devices are designed to amplify differential signals while rejecting common-mode noise, making them ideal for applications like data acquisition, audio processing, and instrumentation. Companies like TI and ADI offer a range of fully differential amplifiers with varying bandwidths, power requirements, and package sizes to cater to diverse engineering needs.
