ADUM6402ARWZ-RL

Overview

The ADUM6402ARWZ-RL is a quad-channel digital isolator from Analog Devices, featuring integrated isoPower isolated DC/DC conversion. It provides galvanic isolation up to 5000 Vrms with magnetic coupling technology. The device supports unidirectional data transmission at rates up to 25 Mb/s and operates within a supply voltage range of 3 V to 5.5 V. Key electrical parameters include a propagation delay of 55 ns, rise/fall times of 2.5 ns, and an operating current of 13 mA. It functions reliably across a temperature range of -40°C to +105°C and is housed in a 16-pin SOIC package.

Feature Summary

• Integrates isolated DC/DC converter for simplified power delivery across isolation barrier
• Provides high common-mode transient immunity via magnetic coupling technology
• Supports high-speed data transmission with low propagation delay characteristics

Applications

• Industrial automation systems requiring robust signal isolation
• Medical equipment needing high-voltage safety compliance
• Power metering applications with galvanic separation requirements

Procurement Notes

Verify the specific suffix RL indicates reel packaging configuration when sourcing. Confirm RoHS compliance status through official manufacturer documentation prior to integration. Ensure design accounts for moisture sensitivity levels indicated in the datasheet. Validate that the 5kV insulation rating meets the specific safety standards required by the end application environment.

Selection Notes

Select this component when both high-speed digital isolation and integrated isolated power are required in a single package. Compare against non-integrated isolators to evaluate board space savings versus external converter complexity. Consider the 55 ns propagation delay for timing-critical interfaces. Verify thermal performance within the SOIC-16 package under maximum load conditions.

Part Context

This part belongs to the ADUM6402 series, which utilizes iCoupler technology for signal and power isolation. It differs from standard isolators by embedding the DC/DC converter, reducing external component count. The ARWZ designation specifies the industrial temperature grade and SOIC-16 package variant within the broader product family.
