ADUM6402ARWZ

Overview

The ADUM6402ARWZ is a quad-channel digital isolator from Analog Devices, utilizing iCoupler magnetic coupling technology. It integrates four independent data channels with an internal isolated DC/DC converter. The device supports unidirectional signal transmission at data rates up to 25 Mb/s. Key electrical parameters include a 5000 Vrms insulation voltage and operation within a supply voltage range of 3 V to 5.5 V. Typical propagation delay is 55 ns, with rise and fall times of 2.5 ns. It operates between -40°C and +105°C in a 16-lead SOIC package.

Feature Summary

• Integrates four high-speed digital isolation channels with an on-chip isolated power supply
• Provides robust galvanic isolation via proprietary magnetic coupling technology
• Supports bidirectional communication through unidirectional channel configuration
• Delivers regulated isolated power output for downstream circuitry

Applications

• Industrial automation systems requiring isolated sensor interfaces
• Medical equipment needing patient isolation barriers
• Power electronics control circuits with high common-mode transient immunity
• Data acquisition systems with multi-channel isolation requirements

Procurement Notes

Verify the specific suffix RL indicates reel packaging when ordering. Confirm RoHS compliance status through official documentation. Check current availability as distribution may be limited. Ensure ESD handling procedures are followed during assembly due to moisture sensitivity classification.

Selection Notes

Select this component when high isolation voltage and integrated power delivery are required. Compare against ADUM6403 if lower propagation delay is critical. Consider ADUM5402 for applications requiring lower insulation ratings but higher power dissipation capabilities. Evaluate thermal management needs based on 400 mW power dissipation rating.

Part Context

Part of the ADuM640x family of quad-channel isolators with integrated DC/DC converters. Shares pinout compatibility with other members in the series while offering distinct performance characteristics. Designed for applications demanding compact solutions with high reliability and long-term stability in harsh environments.

Replacement Considerations

ADUM6403ARWZ offers similar functionality with improved propagation delay specifications. ADUM5402ARWZ provides alternative isolation levels with different power characteristics. Verify pin-to-pin compatibility and electrical parameter alignment before substitution.
