ADUM242D0BRIZ-RL

Overview

The ADUM242D0BRIZ-RL is a robust quad-channel digital isolator from Analog Devices, utilizing iCoupler magnetic coupling technology. It provides four independent isolation channels with a 2:2 channel configuration (two forward, two reverse). The device supports unidirectional data transmission at rates up to 150 Mbps. Key electrical specifications include a 5000 Vrms isolation voltage and a common-mode transient immunity of 75 kV/µs. It operates on a supply voltage range of 1.7 V to 5.5 V with a typical quiescent current of 11 mA per side. Propagation delay is typically 7.2 ns. The component is housed in a 16-lead SOIC package and functions within an operating temperature range of -40°C to +125°C.

Feature Summary

• Robust magnetic coupling technology ensures high reliability against radiated and conducted noise.
• Provides galvanic isolation for four independent bidirectional signal paths.
• High common-mode transient immunity protects against fast-switching noise environments.

Applications

• Industrial automation systems requiring isolated communication interfaces
• Medical equipment needing safe patient isolation barriers
• Power electronics control circuits with high-voltage noise environments

Procurement Notes

Verify the specific suffix 'D0' indicates the correct pinout and functional variant for your design, as Analog Devices uses suffixes to denote package or revision differences. Confirm availability status, as this part may be subject to limited supply or discontinuation notices. Ensure the reel packaging matches your automated assembly requirements. Cross-reference the datasheet version date to ensure compliance with current RoHS and REACH regulations before finalizing procurement orders.

Selection Notes

Select this component when designing systems requiring high-speed digital isolation with strong noise immunity. The 150 Mbps data rate suits most industrial protocols like RS-485 or CAN. Consider the 16-SOIC package size for PCB layout constraints. Verify that the 5000 Vrms isolation rating meets the safety standards required by your target application region. Evaluate the power consumption against battery-operated constraints if applicable.

Part Context

This part belongs to the ADuM242D series of quad-channel digital isolators. It is part of Analog Devices' iCoupler family, which integrates transformer-based isolation technology directly into the CMOS process. This series is designed to replace traditional optocouplers in many applications, offering superior performance in speed, power consumption, and consistency while maintaining small form factors suitable for modern surface-mount assembly techniques.

Replacement Considerations

Check for direct equivalents within the ADuM242E series, such as the ADUM242E1BRIZ-RL, which offers similar functionality but may have updated specifications or packaging options. Verify pin compatibility and electrical parameter overlaps before substitution. Consult official Analog Devices documentation for any obsolescence notices regarding the D-series variants.
