ADUM4402BRIZ-RL

Overview

The ADUM4402BRIZ-RL is a quad-channel digital isolator from Analog Devices, utilizing magnetic coupling technology to provide electrical isolation. It features four independent channels with unidirectional signal transmission capability. The device operates within a supply voltage range of 2.7 V to 5.5 V and supports data rates up to 90 Mb/s. Key electrical specifications include an insulation voltage of 5000 Vrms, a typical propagation delay of 32 ns, and rise/fall times of 3 ns. It draws 830 uA of operating power current and functions reliably across a temperature range of -40°C to +105°C.

Feature Summary

• Provides robust galvanic isolation between circuits using magnetic coupling technology
• Supports high-speed digital signal transmission with low propagation delay
• Offers wide common-mode transient immunity for noise-sensitive applications

Applications

• Industrial automation systems requiring isolated communication interfaces
• Medical equipment needing patient isolation barriers
• Power electronics control circuits with high-voltage separation requirements

Procurement Notes

Verify component authenticity through authorized distributors or direct manufacturer channels. Confirm RoHS compliance status and check for specific lot traceability requirements. Ensure storage conditions meet humidity sensitivity levels to prevent package damage prior to assembly. Validate that the SOIC-16 package dimensions align with your PCB footprint design constraints.

Selection Notes

Select this component when bidirectional isolation is not required, as it supports only unidirectional data flow. Consider the 90 Mb/s data rate limit against your system's bandwidth needs. Evaluate the 5000 Vrms insulation rating against your circuit's isolation voltage requirements. Assess the 830 uA power consumption against battery-operated or low-power design constraints.

Part Context

This part belongs to the ADUM4402 series of general-purpose digital isolators. It shares the same core isolation architecture but differs in packaging and reel configuration compared to non-RL variants. The BRIZ suffix indicates the specific temperature grade and tape-and-reel packaging format suitable for automated surface-mount assembly processes.
