Digital Isolators are specialized electronic components designed to enable signal transmission between two isolated circuits while effectively blocking high voltages and noise from one side to the other. This ensures data integrity and protection against electrical hazards. The main function of these devices is to transmit digital signals across an isolation barrier, which safeguards sensitive electronic components and user interfaces from dangerous voltage levels. They are commonly employed in environments where signal integrity and insulation from high voltages are critical.
These isolators find extensive applications in industries such as medical equipment, where patient safety is paramount, and in industrial automation systems, which require robust noise immunity and safety isolation to operate reliably. Digital Isolators are characterized by their ability to support high data rates, robustness against electromagnetic interference, and low power consumption. Some of the leading manufacturers in the field of Digital Isolators include Texas Instruments, Analog Devices, and Silicon Labs.
