ADUM242D1BRIZ

Overview

The ADUM242D1BRIZ is a general-purpose digital isolator from Analog Devices' iCoupler series, utilizing magnetic coupling technology to provide robust signal isolation. It features four independent channels with a unidirectional configuration, supporting data rates up to 150 Mbps. The device offers a high common-mode transient immunity of 75 kV/µs and an insulation voltage rating of 5000 Vrms. Operating within a supply voltage range of 1.7 V to 5.5 V, it ensures reliable performance across a wide temperature range from -40°C to +125°C. Packaged in a 16-lead SOIC, it integrates CMOS technology for low power consumption and minimal propagation delay.

Feature Summary

• Provides robust 5000 Vrms isolation across four independent channels using proprietary iCoupler magnetic coupling technology.
• Delivers high-speed data transmission capabilities with a maximum data rate of 150 Mbps and low propagation delay.
• Ensures signal integrity in noisy environments through exceptional common-mode transient immunity of 75 kV/µs.
• Supports flexible logic interface operation with a wide single-supply voltage range from 1.7 V to 5.5 V.

Applications

• Industrial automation systems requiring galvanic isolation between microcontrollers and peripheral devices.
• Medical equipment needing safe patient isolation and protection against electrical hazards.
• Power electronics interfaces for monitoring and control circuits in inverters and motor drives.
• Automotive electronic systems demanding reliable communication across different ground potentials.

Procurement Notes

Verify the specific suffix 'D1' to confirm the unidirectional channel configuration and pinout compatibility with your design. Ensure the 16-SOIC package dimensions align with your PCB footprint constraints. Check for RoHS compliance status if required by your manufacturing standards. Confirm availability as distribution status may vary due to supply chain conditions. Validate that the operating temperature range meets your environmental requirements.

Selection Notes

Select this component when four isolated bidirectional or unidirectional channels are needed for digital signal transmission. Consider the 150 Mbps data rate limit for high-speed applications. Evaluate the 75 kV/µs CMTI specification for environments with rapid voltage transients. Compare power consumption metrics against other isolators if battery life is critical. Ensure the 5000 Vrms isolation rating satisfies safety regulations for your specific application sector.

Part Context

This part belongs to the ADuM242 family of quad-channel digital isolators. It shares the core iCoupler technology with variants like ADUM242E1BRIZ but differs in specific configuration parameters. The family is designed for cost-effective isolation solutions in industrial and consumer markets. It complements Analog Devices' broader portfolio of isolation products including gate drivers and isolated ADCs.

Replacement Considerations

The ADUM242E1BRIZ-RL is a verified substitute within the same product family offering similar isolation characteristics. Verify pin-to-pin compatibility and functional equivalence before substitution. Ensure the replacement variant meets all electrical specifications required by the original design. Check datasheet updates for any changes in recommended operating conditions or packaging options.
