ADUM240E1BRIZ-RL

Overview

The ADUM240E1BRIZ-RL is a quad-channel digital isolator from Analog Devices, utilizing iCoupler magnetic coupling technology. It operates within a supply voltage range of 1.7 V to 5.5 V and provides an isolation voltage of 5000 Vrms. The device supports data rates up to 150 Mbps with a typical propagation delay of 13 ns. It features a high common-mode transient immunity of 75 kV/µs and is housed in a 16-SOIC package. The component functions as a unidirectional isolator suitable for robust signal transmission across isolated boundaries.

Feature Summary

• Integrates four independent channels using proprietary iCoupler magnetic coupling technology for reliable signal isolation.
• Provides high common-mode transient immunity to maintain signal integrity in electrically noisy environments.
• Supports wide operating temperature ranges and low power consumption profiles for efficient system design.

Applications

• Industrial automation systems requiring robust galvanic isolation
• Medical equipment needing certified safety isolation barriers
• Power metering applications involving high-voltage sensing

Procurement Notes

Verify the specific suffix E1 against official Analog Devices documentation to confirm electrical characteristics and pinout compatibility. Ensure the SOIC-16 package dimensions match your PCB footprint requirements. Confirm that the unidirectional channel configuration aligns with your circuit topology before finalizing procurement orders.

Selection Notes

Select this component when four isolated bidirectional or unidirectional channels are required within a single compact package. Consider the 150 Mbps data rate and 75 kV/µs CMTI specifications for high-speed industrial interfaces. Evaluate the 1.7 V to 5.5 V supply range compatibility with your system logic levels and power constraints.
