ADUM5401CRWZ-RL

Overview

The ADUM5401CRWZ-RL is a quad-channel digital isolator from Analog Devices, featuring an integrated DC-to-DC converter. It provides unidirectional signal isolation with a data rate of 25 Mbps and a common-mode transient immunity of 25 kV/µs. The device operates on a supply voltage range of 3 V to 5.5 V, with a maximum propagation delay of 60 ns. It utilizes magnetic coupling technology for isolation, rated at 2500 Vrms. The component is housed in a 16-SOIC package and supports an operating temperature range from -40°C to +105°C.

Feature Summary

• Integrates a high-efficiency isolated DC-to-DC converter to power the secondary side circuitry.
• Provides four independent unidirectional signal channels with fail-safe output functionality.
• Features robust magnetic coupling technology ensuring high common-mode transient immunity.

Applications

• Industrial automation and process control systems
• Isolated communication interfaces such as RS-485 and CAN bus
• Smart grid and energy metering equipment
• Medical instrumentation requiring galvanic isolation

Procurement Notes

Verify that the specific suffix '-RL' corresponds to the reel packaging format required for automated surface-mount assembly processes. Confirm that the integrated DC-to-DC converter specifications align with the target application's power budget and voltage requirements. Ensure compliance with RoHS directives and check for any moisture sensitivity level restrictions during storage and handling.

Selection Notes

Select this component when a single IC solution is needed to provide both signal isolation and isolated power generation. It is suitable for designs requiring four independent channels with high-speed data transmission capabilities. Consider the thermal performance of the integrated converter and the total power dissipation limits within the SOIC-16 package when designing the PCB layout.

Part Context

This part belongs to the ADUM540x series of IsoPower digital isolators. These devices combine analog and RF components on a CMOS process to create fully integrated isolation solutions. The series is designed to replace traditional optocouplers and transformer-based solutions, offering superior performance, smaller footprint, and better reliability in harsh industrial environments.

Replacement Considerations

Direct replacements may include other variants within the ADUM540x family, such as the ADUM5401CRWZ (tube package) or ADUM5401WCRWZ-1 (automotive qualified). Verify pin compatibility and electrical parameters before substitution.
