Instrumentation amplifiers are not a specific brand but a category of precision amplifiers used in industrial and scientific applications. Key manufacturers include Texas Instruments (USA), Analog Devices (USA), and STMicroelectronics (Switzerland). These amplifiers are designed for high accuracy, low noise, and signal conditioning in sectors like medical devices, process control, and test equipment. Products often feature differential inputs, high common-mode rejection, and programmable gain, serving industries such as automation, aerospace, and biomedical engineering.
