ADUM242D1BRIZ-RL

Overview

The ADUM242D1BRIZ-RL is a robust quad digital isolator from Analog Devices, utilizing iCoupler magnetic coupling technology. It provides four independent channels with a 2:2 configuration (two forward, two reverse) in a 16-pin SOIC package. The device supports data rates up to 150 Mb/s and offers an insulation voltage of 5000 Vrms. It operates on a supply voltage range of 1.7 V to 5.5 V, with a typical operating current of 11 mA. Key performance metrics include a propagation delay of 7.2 ns and a common-mode transient immunity of 75 kV/µs. The component functions within a temperature range of -40°C to +125°C.

Feature Summary

• Integrates four isolated channels using proprietary iCoupler magnetic coupling technology for signal transmission across isolation barriers.
• Provides high common-mode transient immunity to reject noise spikes in electrically noisy environments.
• Supports unidirectional data flow with configurable channel orientation for flexible system design.
• Operates over an extended industrial temperature range suitable for demanding applications.

Applications

• Industrial automation systems requiring galvanic isolation between control logic and sensors
• Medical equipment needing reliable signal isolation for patient safety compliance
• Power electronics interfaces for monitoring and control circuits in inverters or converters

Procurement Notes

Verify the specific suffix D1BRIZ against the official datasheet to confirm the exact channel configuration and packaging variant. Confirm RoHS compliance status and lead times directly with authorized distributors, as availability may be restricted. Ensure the ordering part number matches the required reel quantity and tape-and-reel specifications for automated assembly processes.

Selection Notes

Select this component when four isolated bidirectional channels are required within a single package. Compare propagation delay and power consumption against other iCoupler variants if low latency or ultra-low power is critical. Verify that the 5000 Vrms isolation rating meets the safety standards of the target application. Consider the 16-SOIC footprint constraints during PCB layout planning.

Part Context

This part belongs to the ADuM242 series of quad digital isolators. It shares the core iCoupler architecture with related models like the ADUM242E1BRIZ-RL but differs in specific electrical characteristics and qualification levels. The series is designed to replace traditional transformer and optocoupler solutions in space-constrained designs.

Replacement Considerations

The ADUM242E1BRIZ-RL is a documented alternative within the same family. Verify functional compatibility regarding channel count, data rate, and isolation voltage before substitution. Check for differences in operating temperature ranges and supply current requirements to ensure system stability.
