ADUM2401ARWZ-RL

Overview

The ADUM2401ARWZ-RL is a quad-channel digital isolator utilizing iCoupler magnetic coupling technology. It provides bidirectional communication with four independent channels configured as three inputs and one output. The device operates within a supply voltage range of 2.7 V to 5.5 V and supports data rates up to 1 Mbps. It features a high isolation voltage of 5000 Vrms and a common-mode transient immunity of 25 kV/µs. Propagation delay is typically 65 ns, with rise and fall times of approximately 3 ns. It functions reliably across an operating temperature range of -40°C to +105°C in a 16-lead SOIC package.

Feature Summary

• Implements iCoupler magnetic coupling technology for robust signal isolation without external transformers.
• Provides four independent digital channels supporting unidirectional data flow from input to output sides.
• Delivers high common-mode transient immunity to maintain signal integrity in noisy environments.
• Supports standard 3 V and 5 V logic level translation for versatile interface compatibility.

Applications

• Industrial automation systems requiring galvanic isolation between control and power stages
• Medical equipment needing safe patient isolation interfaces
• Power metering circuits for accurate signal transmission across potential differences

Procurement Notes

Verify the specific suffix ARWZ-RL against the original design specification to ensure correct packaging and tape-and-reel configuration. Confirm that the 16-SOIC wide body footprint matches the PCB layout requirements. Check current availability status as distribution may vary by region. Ensure compliance with RoHS3 standards if required by the target market regulations.

Selection Notes

Select this component when four isolated channels are necessary for unidirectional data transfer. It is suitable for applications demanding high common-mode noise rejection and reliable operation at elevated temperatures. Consider the 1 Mbps data rate limit and 5000 Vrms isolation barrier when designing safety-critical interfaces. Evaluate the 16-lead SOIC package constraints against available board space.

Part Context

This part belongs to the ADuM240x family of quad-channel digital isolators from Analog Devices. It shares the same core architecture and specifications as the ADUM2400 and ADUM2402, differing primarily in channel directionality configurations. The series utilizes CMOS technology integrated with micro-transformer coils on a silicon substrate.

Replacement Considerations

The ADUM2401ARIZ-RL serves as a direct pin-compatible alternative featuring the narrower SOIC-16 package instead of the wide variant. Other family members like the ADUM2400 or ADUM2402 offer similar electrical characteristics but differ in channel direction settings.
