ADUM2401CRWZ

Overview

The ADUM2401CRWZ is a quad-channel digital isolator from Analog Devices, utilizing iCoupler magnetic coupling technology. It operates within a supply voltage range of 2.7 V to 5.5 V and supports data rates up to 120 Mb/s. The device features unidirectional signal transmission with a typical propagation delay of 27 ns. It provides an insulation voltage rating of 5000 Vrms and functions reliably across an operating temperature range of -40°C to +105°C. Packaged in a 16-lead SOIC format, it integrates high-speed isolation for robust signal integrity.

Feature Summary

• Integrates four independent digital isolation channels using proprietary iCoupler magnetic technology
• Supports high-speed data transmission with rates up to 120 Mb/s
• Provides reinforced electrical isolation rated at 5000 Vrms
• Operates bidirectionally on power lines while maintaining unidirectional signal paths

Applications

• Industrial automation systems requiring galvanic isolation
• Medical equipment needing safety-certified signal separation
• Power electronics interfaces for motor control circuits
• Test and measurement instrumentation isolation barriers

Procurement Notes

Verify the specific suffix CRWZ against official Analog Devices documentation to confirm package type and temperature grade. Confirm current availability status as distribution listings may indicate limited stock or discontinuation. Ensure compliance with RoHS directives and moisture sensitivity levels required for your assembly process before finalizing procurement orders.

Selection Notes

Select this component when four isolated channels are required with high data throughput capabilities. The unidirectional configuration suits applications where signal flow is strictly one-way. Consider the 16-lead SOIC package constraints for PCB layout. Evaluate power consumption requirements as the device draws significant quiescent current during operation compared to lower-speed alternatives.

Part Context

This part belongs to the ADuM240x family of quad-channel digital isolators. It shares architectural similarities with the ADUM2400 and ADUM2402 but differs in channel directionality and specific performance metrics. The series leverages silicon dioxide insulation layers for reliable long-term isolation performance in harsh electromagnetic environments.

Replacement Considerations

Check Analog Devices datasheets for direct pin-compatible substitutes within the ADUM240x series. Verify that alternative parts match the 5000 Vrms insulation rating and 120 Mb/s data rate specifications. Ensure the replacement maintains the same SOIC-16 footprint and thermal characteristics.
