Difference amplifiers are not a specific brand but a type of electronic component used in industrial and scientific applications. These amplifiers are designed to measure the difference between two input signals, commonly used in instrumentation, control systems, and signal processing. Companies like Texas Instruments (USA), Analog Devices (USA), and STMicroelectronics (Switzerland) produce difference amplifiers as part of their broader product lines. These devices serve industries such as automotive, aerospace, medical equipment, and industrial automation. Key products include precision difference amplifiers, instrumentation amplifiers, and operational amplifiers, which are available through distributors like Radwell and Grainger.
