ADUM241E0BRIZ-RL

Overview

The ADUM241E0BRIZ-RL is a general-purpose digital isolator from Analog Devices, utilizing iCoupler magnetic coupling technology. It features four isolated channels configured as three forward and one reverse path. The device supports data rates up to 150 Mbps with a typical propagation delay of 7.2 ns. It offers an insulation voltage of 5000 Vrms and a common-mode transient immunity of 75 kV/µs. Operating on a single supply voltage between 1.7 V and 5.5 V, it draws 11.4 mA of supply current. The component is housed in a 16-SOIC package and is qualified under AEC-Q100 standards for automotive applications.

Feature Summary

• Robust galvanic isolation using proprietary iCoupler magnetic coupling technology
• High common-mode transient immunity ensuring signal integrity in noisy environments
• AEC-Q100 qualification for reliability in automotive electronic systems

Applications

• Automotive engine control units requiring robust signal isolation
• Industrial communication interfaces such as CAN and LIN bus systems
• Medical equipment needing high-voltage isolation for safety compliance

Procurement Notes

Verify the specific suffix 'E0' against design requirements, as it denotes the channel configuration variant within the ADuM241 family. Confirm that the 16-SOIC package dimensions align with the PCB footprint. Ensure the operating temperature range meets system specifications. Check for RoHS3 compliance status if required by regional regulations. Validate supply chain availability due to potential limited stock conditions.

Selection Notes

Select this component when a 3:1 channel ratio is required for unidirectional signal transmission. The 5000 Vrms isolation rating suits applications demanding high dielectric strength. Consider the 150 Mbps data rate limit for bandwidth requirements. The 1.7 V to 5.5 V supply range allows compatibility with various logic levels. Evaluate the 11.4 mA power consumption against thermal constraints in enclosed designs.

Part Context

This part belongs to the ADuM241 series of quad digital isolators. It shares the core iCoupler architecture with variants like ADUM241E1 and ADUM241D0, differing primarily in channel directionality and qualification grades. The series is designed to replace traditional optocouplers in space-constrained, high-speed digital isolation applications.

Replacement Considerations

The ADUM241E1BRIZ is a functional substitute with identical electrical characteristics but a different channel configuration (1:3). Verify that the reversed channel direction matches the circuit design before substitution.
