Working Principles

ADM1490EBRMZ is a digital isolator that uses capacitive coupling and proprietary iCoupler® technology to transmit digital signals across an isolation barrier. The device consists of four independent channels, each capable of isolating and shifting logic-level signals between two different voltage domains. The input signal is converted into a high-frequency digital signal, transmitted across the isolation barrier, and then reconstructed into the output signal on the other side.

Detailed Application Field Plans

1. Industrial Automation: ADM1490EBRMZ can be used to isolate and interface control signals between different subsystems in industrial automation applications, ensuring safety and preventing ground loop issues.
2. Medical Devices: It can be employed in medical devices to provide isolation between sensitive patient monitoring circuits and external systems, protecting patients from potential electrical hazards.
3. Power Electronics: The digital isolator can be utilized in power electronics applications to isolate control signals between low-voltage control circuits and high-voltage power circuits, enhancing system reliability and safety.
