ADUM142E0BRZ-RL7

Digital Isolators Overview

The ADUM142E0BRZ-RL7 is a quad-channel digital isolator from Analog Devices, utilizing iCoupler magnetic coupling technology. It provides four independent isolation channels with two forward and two reverse directions. Key electrical parameters include a data rate of 150 Mb/s, an insulation voltage of 3000 Vrms, and a common-mode transient immunity of 75 kV/µs. The device operates on a supply voltage range of 1.8 V to 5 V, with a typical operating current of 11 mA per channel. It features a propagation delay of 15 ns and rise/fall times of 2.5 ns. The component is housed in a 16-pin SOIC package and supports an operating temperature range from -40°C to +125°C.

Digital Isolators Feature Summary

• Integrates four isolated digital channels using proprietary iCoupler magnetic coupling technology for high-speed signal transmission.
• Provides robust isolation performance with a 3000 Vrms insulation rating and high common-mode transient immunity.
• Supports bidirectional data communication with configurable polarity for flexible system integration.

Digital Isolators Applications

• Industrial automation systems requiring galvanic isolation between microcontrollers and peripheral devices.
• Medical equipment interfaces needing certified isolation barriers for patient safety.
• Power electronics control circuits isolating gate drivers from low-voltage logic controllers.

Digital Isolators Procurement Notes

Verify the specific suffix 'E0' against the required datasheet revision, as it denotes specific insulation ratings distinct from other variants like 'E1'. Confirm availability status directly with authorized distributors, as supply constraints may apply. Ensure the SOIC-16 package width matches the PCB footprint design. Validate RoHS compliance documentation prior to final procurement approval.

Digital Isolators Selection Notes

Select this component when four isolated channels are required within a single package to save board space. Compare the 150 Mb/s data rate against application timing requirements. Evaluate the 3000 Vrms isolation level against regulatory standards such as IEC 60601 or UL 1577. Consider the 1.8 V to 5 V supply range compatibility with the target logic family.

Digital Isolators Part Context

This part belongs to the ADuM142E series of quad-channel digital isolators. It shares the same physical package and basic functionality with the ADUM142E1BRZ-RL7, differing primarily in the specific insulation certification and voltage ratings associated with the 'E0' designation. Both variants utilize the same iCoupler architecture for reliable signal isolation.

Digital Isolators Replacement Considerations

The ADUM142E1BRZ-RL7 is a direct functional substitute within the same series, offering identical pinout and performance characteristics with potentially different insulation certifications. Verify that the replacement variant meets the specific isolation voltage requirements of the design before substitution.
