ADUM3402BRWZ-RL

Overview

The ADUM3402BRWZ-RL is a quad-channel digital isolator utilizing iCoupler magnetic coupling technology. It operates within a supply voltage range of 2.7 V to 5.5 V and supports data rates up to 10 Mb/s. Key electrical parameters include a maximum propagation delay of 50 ns, typical rise and fall times of 3 ns, and an insulation voltage of 2500 Vrms. The device features bidirectional channels, a common-mode transient immunity of 25 kV/µs, and operates across a temperature range of -40°C to +105°C.

Feature Summary

• Integrates four independent bidirectional digital isolation channels using monolithic air core transformer technology.
• Provides high-speed signal transmission with low propagation delay and pulse width distortion.
• Offers robust electromagnetic interference immunity through magnetic coupling without requiring external components.

Applications

• Industrial automation systems requiring isolated communication interfaces
• Medical equipment needing galvanic isolation for safety compliance
• Power electronics control circuits with high-voltage noise environments

Procurement Notes

Verify the specific suffix RL indicates reel packaging when sourcing. Confirm RoHS compliance status through official manufacturer documentation. Check current availability as distribution may vary by region. Ensure the SOIC-16 package matches your PCB footprint requirements before finalizing orders.

Selection Notes

Select this component for applications requiring four isolated channels in a compact surface-mount package. Compare power consumption against other iCoupler variants if battery life is critical. Verify that the 10 Mb/s data rate meets system timing requirements. Consider thermal performance within the specified operating temperature range during design integration.
