ADUM1401CRWZ-RL

Overview

The ADUM1401CRWZ-RL is a quad-channel digital isolator from Analog Devices, utilizing iCoupler technology. It features a 3/1 channel directionality configuration within a 16-SOIC package. Key electrical parameters include a data rate of 120 Mb/s and an isolation voltage of 2500 Vrms. The device operates on supply voltages between 2.7 V and 5.5 V, with typical propagation delays of 27 ns and rise/fall times of 3 ns. It supports a common-mode transient immunity of 25 kV/µs and functions within a temperature range of -40°C to +105°C.

Feature Summary

• Integrates high-speed CMOS logic with single-chip air-core transformer technology for magnetic coupling isolation.
• Provides robust signal isolation with high common-mode transient immunity capabilities.
• Supports multi-voltage domain interfaces without requiring isolated power supplies.

Applications

• General-purpose multichannel isolation
• SPI interface isolation
• Data converter isolation
• RS-232, RS-422, and RS-485 transceiver isolation

Procurement Notes

Verify component authenticity through authorized distributors or direct manufacturer channels. Confirm the specific suffix 'RL' indicates reel packaging if required for automated assembly processes. Check current availability status as supply constraints may affect immediate procurement. Ensure compliance with RoHS directives and verify operating temperature ranges match application requirements before finalizing orders.

Selection Notes

Select this component when four independent isolation channels are required in a compact surface-mount footprint. The 3/1 directionality suits applications where three signals flow one way and one returns. Consider the 120 Mb/s data rate for high-speed serial communication needs. Evaluate the 2500 Vrms isolation rating against system safety standards. Compare power consumption figures against battery-operated constraints if applicable.

Part Context

This part belongs to the ADuM1400/ADuM1401/ADuM1402 series of quad-channel digital isolators. These devices represent Analog Devices' implementation of iCoupler technology, replacing traditional optocouplers. The series offers improved performance characteristics including lower power consumption and higher reliability compared to legacy isolation technologies.
