ADUM5402WXRWZ

Overview

The ADUM5402WXRWZ is a quad-channel digital isolator featuring an integrated isoPower isolated DC-to-DC converter. Based on iCoupler technology, it provides up to 500 mW of regulated isolated power at 3.3 V or 5.0 V. The device offers four DC-to-25 Mbps signal isolation channels in a 16-lead SOIC package with a 7.6 mm creepage distance. It supports high common-mode transient immunity exceeding 25 kV/µs and operates within a temperature range of -40°C to +105°C.

Feature Summary

• Integrated isoPower isolated DC-to-DC converter eliminates the need for separate isolated power supplies
• Four unidirectional signal channels support data rates up to 25 Mbps
• High common-mode transient immunity ensures reliable signal transmission in noisy environments
• Qualified for automotive applications with extensive safety and regulatory approvals
