Isolated interface ICs are not a specific brand but a category of integrated circuits designed to provide electrical isolation between different parts of an electronic system, ensuring safety and signal integrity. These ICs are widely used in industries such as industrial automation, medical equipment, automotive, and telecommunications, where noise immunity and high-voltage protection are critical. Leading manufacturers of isolated interface ICs include Texas Instruments (USA), Analog Devices (USA), and Infineon Technologies (Germany). Their products often feature galvanic isolation, high-speed data transmission, and robust performance in harsh environments. These components are essential for applications like motor control, power supplies, and communication interfaces.
