ADUM6404ARWZ-RL

Overview

The ADUM6404ARWZ-RL is a quad-channel digital isolator from Analog Devices, featuring an integrated isolated DC/DC converter. It provides 5000 Vrms insulation voltage and supports data rates up to 25 Mb/s with unidirectional signal transmission. The device operates on a supply voltage range of 3 V to 5.5 V, delivering up to 400 mW output power from the internal converter. Key electrical parameters include a propagation delay of 60 ns and rise/fall times of 2.5 ns. It functions within a temperature range of -40°C to +105°C and is housed in a 16-pin SOIC package.

Feature Summary

• Integrates an isolated DC/DC converter for simplified power delivery across isolation barriers
• Provides magnetic coupling-based isolation for four independent signal channels
• Supports high-speed data transmission at rates up to 25 Mb/s
• Offers robust insulation capability rated at 5000 Vrms

Applications

• Industrial automation systems requiring galvanic isolation
• Medical equipment needing safe patient isolation
• Power metering and energy monitoring circuits
• Inverter control and motor drive interfaces

Procurement Notes

Verify the specific suffix 'ARWZ-RL' against official Analog Devices documentation to confirm the exact package variant and reel configuration. Ensure compatibility with moisture sensitivity levels and reflow soldering profiles specified in the datasheet. Cross-reference the manufacturer part number directly with authorized distributors to avoid counterfeit components.

Selection Notes

Select this component when a single-chip solution combining signal isolation and isolated power generation is required. It is suitable for designs needing 5000 Vrms isolation with four bidirectional or unidirectional channels. Consider the 400 mW power limit of the internal converter when sizing external loads. Verify that the 25 Mb/s data rate meets system timing requirements.
