Isolated comparators refer to a category of electronic components rather than a specific brand. These devices are widely used in industrial and automotive applications for signal conditioning, voltage monitoring, and noise immunity. Major manufacturers producing isolated comparators include Texas Instruments (USA), Analog Devices (USA), and STMicroelectronics (Switzerland). These companies provide high-performance isolated comparators designed for harsh environments, serving industries such as power management, motor control, and industrial automation. Key products include optocoupler-based isolators and digital isolators with integrated comparators, ensuring safety and reliability in high-voltage systems.
