ADUM242E0BRWZ

Overview

The ADUM242E0BRWZ is a quad-channel digital isolator from Analog Devices, utilizing iCoupler magnetic coupling technology. It provides four independent channels with two forward and two reverse paths in a 16-pin SOIC package. Key electrical parameters include a maximum data rate of 150 Mbps, an insulation voltage of 5000 Vrms, and a common-mode transient immunity of 75 kV/µs. The device operates on a supply voltage range of 1.7 V to 5.5 V with a typical quiescent current of 11 mA. Propagation delay is specified at 7.2 ns, with rise and fall times of 2.5 ns. It functions within a temperature range of -40°C to +125°C.

Feature Summary

• Robust isolation architecture based on iCoupler technology for high noise immunity
• Quad-channel configuration supporting bidirectional signal transmission
• High common-mode transient immunity to suppress noise interference
• Low propagation delay ensuring precise timing synchronization

Applications

• Industrial automation systems requiring galvanic isolation
• Medical equipment needing reliable signal separation
• Power electronics control circuits
• Data acquisition systems with noisy environments

Procurement Notes

Verify the specific suffix 'WZ' indicates the wider SOIC-16 package (7.50mm width) compared to standard variants. Confirm RoHS compliance status through official manufacturer documentation prior to integration. Ensure ESD handling protocols are followed during assembly due to moisture sensitivity classification. Cross-reference pinout diagrams with the latest datasheet revision to avoid layout errors.

Selection Notes

Select this component when a quad-channel isolator with unidirectional or bidirectional capability is required. Compare against the ADUM242E0BRIZ if a narrower SOIC-16 package is preferred. Consider the ADUM342E0BRWZ if higher insulation voltage (10000 Vrms) or shutdown functionality is needed. Evaluate power consumption requirements as this device draws approximately 11 mA per side.

Part Context

This part belongs to the ADuM242E series of robust quad-channel digital isolators. It leverages Analog Devices' proprietary iCoupler technology to replace traditional optocouplers. The series is designed for applications demanding high reliability and low latency. It serves as a direct replacement for legacy isolation solutions in space-constrained designs.

Replacement Considerations

The ADUM242E0BRIZ is a compatible alternative offering identical electrical performance but housed in a narrower SOIC-16 package. Verify footprint compatibility before substitution. No other direct functional equivalents are confirmed in the provided documentation.
