ADUM242E0BRIZ-RL

Overview

The ADUM242E0BRIZ-RL is a general-purpose digital isolator from Analog Devices Inc. featuring four unidirectional channels in a 16-SOIC package. It utilizes magnetic coupling technology to provide robust signal isolation with an insulation voltage of 5000 Vrms and a common-mode transient immunity of 75 kV/µs. The device supports data rates up to 150 Mb/s, operates on supply voltages between 1.7 V and 5.5 V, and functions within a temperature range of -40°C to +125°C.

Feature Summary

• Provides galvanic isolation across four independent unidirectional channels using iCoupler magnetic coupling technology.
• Delivers high common-mode transient immunity of 75 kV/µs for reliable operation in electrically noisy environments.
• Supports data transmission rates up to 150 Mb/s with low propagation delay characteristics.

Applications

• Industrial automation systems requiring robust signal isolation
• Medical equipment needing high-voltage safety barriers
• Power management circuits for isolated communication interfaces

Procurement Notes

Verify the specific suffix E0 against official Analog Devices documentation to confirm exact electrical parameters and pinout configuration. Confirm RoHS compliance status and check current availability through authorized distributors as supply may be restricted. Ensure the 16-SOIC package dimensions match your PCB layout requirements before finalizing procurement.

Selection Notes

Select this component when four-channel unidirectional isolation is required with high voltage withstand capabilities. Consider the 150 Mb/s data rate limit and 5000 Vrms insulation rating for system design. Evaluate the 1.7 V to 5.5 V operating range against your logic levels. Compare against other ADUM242 variants if bidirectional channels or different packaging options are needed.

Part Context

This part belongs to the ADuM242 series of quad-channel digital isolators by Analog Devices. These devices integrate CMOS sensor technology with air-core transformer coils to transmit signals across isolation barriers without optical components. The series offers alternatives to traditional optocouplers with improved performance metrics and smaller form factors.

Replacement Considerations

Check Analog Devices datasheets for direct substitutes like the ADUM242D0BRIZ-RL or ADUM242E1BRIZ-RL. Verify that alternative parts maintain identical channel counts, isolation ratings, and package types. Ensure functional compatibility regarding data rates and supply voltage ranges before substitution.
