ADUM6403ARWZ-RL

Overview

The ADUM6403ARWZ-RL is a four-channel digital isolator from Analog Devices, housed in a 16-pin SOIC package. It integrates an isolated DC/DC converter to provide power across the isolation barrier. The device supports data rates up to 25 Mb/s with a typical propagation delay of 60 ns and rise/fall times of 2.5 ns. It offers 5000 Vrms insulation voltage and operates within a supply voltage range of 3 V to 5.5 V. The component functions unidirectionally and maintains performance across an industrial temperature range of -40°C to +105°C.

Feature Summary

• Integrates an isolated DC/DC converter for on-board power delivery across the 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 galvanic isolation
• Medical equipment needing reinforced safety isolation
• Power metering and energy monitoring circuits

Procurement Notes

Verify the specific suffix RL indicates reel packaging when ordering. Confirm the A grade designation matches required operating temperature ranges. Ensure the SOIC-16 footprint aligns with PCB layout constraints. Check current availability status as distribution may vary by region. Validate RoHS compliance documentation for regulatory requirements.

Selection Notes

Choose this component when integrated isolated power is necessary to simplify design. Select for applications demanding high CMTI and reliable signal integrity. Consider the 16-pin SOIC form factor for space-constrained layouts. Evaluate the 25 Mb/s speed against system timing requirements. Assess thermal management needs based on 400 mW power dissipation.

Part Context

This part belongs to the ADUM6403 series of digital isolators. It utilizes Analog Devices' iCoupler technology for signal transmission. The device combines four logic channels with a switching regulator. It serves as a complete isolation solution for mixed-signal systems.

Replacement Considerations

Check for direct pin-compatible substitutes within the ADUM64xx family. Verify if alternative models offer different channel counts or voltage ratings. Ensure any replacement maintains the same SOIC-16 package outline.
