ADUM5402CRWZ-RL

Overview

The ADUM5402CRWZ-RL is a quad-channel digital isolator from Analog Devices, featuring an integrated isoPower isolation DC/DC converter. It provides four independent signal channels with a data rate of up to 25 Mb/s and a propagation delay of 60 ns. The device operates on a supply voltage range of 3 V to 5.5 V and delivers a maximum output power of 500 mW at regulated 3.3 V or 5.0 V outputs. It offers an insulation voltage of 2500 Vrms and supports unidirectional signal transmission. The component is housed in a 16-pin SOIC package with a creepage distance of 7.6 mm and functions within a temperature range of -40°C to +105°C.

Feature Summary

• Integrates an isoPower isolated DC/DC converter for efficient power delivery across the isolation barrier
• Provides four independent high-speed signal channels for complex system isolation requirements
• Utilizes magnetic coupling technology to ensure robust electrical isolation between circuits

Applications

• Industrial automation systems requiring galvanic isolation
• Medical equipment needing safe patient isolation
• Power management circuits with negative high voltage rails
• Current sensor evaluation boards

Procurement Notes

Verify the specific suffix (CRWZ-RL) against official Analog Devices documentation to confirm the exact package type, temperature grade, and reel packaging specifications. Ensure compatibility with PCB layout guidelines regarding radiation standards due to the integrated switching converter. Confirm moisture sensitivity levels and storage conditions prior to assembly.

Selection Notes

Select this component when a single IC solution is required to provide both signal isolation and isolated power generation. It is suitable for designs needing four isolated channels with moderate data rates. Consider the thermal dissipation capabilities and PCB layout constraints associated with the internal DC/DC converter when choosing this part over separate isolator and converter components.

Part Context

This part belongs to the ADuM540x series of quad-channel digital isolators. These devices are designed to replace traditional optocouplers and transformer-based solutions, offering higher reliability and smaller form factors. The series includes variants with different channel configurations and power outputs, all sharing the core isoPower technology for integrated isolation.
