What is a Digital isolator?

A digital isolator is a device that transmits digital signals while providing electrical isolation between different circuits. Compared to traditional optoisolators (photocouplers), digital isolators are faster, more energy-efficient, and compact. They operate using capacitive coupling, magnetic coupling, or radio frequency (RF) coupling technologies, offering high reliability and noise immunity. Digital isolators are widely used in industrial equipment, power management, medical devices, and data communication, enhancing electrical safety and data transmission quality.

Application of Digital isolator

✅Industrial Control Systems
Provides isolation of digital signals between motor controllers and PLCs, ensuring equipment and operator safety.
✅Power Management Circuits
Offers isolation between high-voltage and low-voltage circuits, protecting against overvoltage and surges.
✅Medical Devices
Ensures electrical isolation between patients and electronic devices, enhancing the safety of medical equipment.
✅Communication Networks
Minimizes noise interference during data transmission, enabling high-quality communication.
