ADUM6202ARWZ

Overview

The ADUM6202ARWZ is a dual-channel digital isolator from Analog Devices, featuring an integrated isoPower isolated DC/DC converter. It provides two unidirectional signal channels with a data rate of 25 Mb/s and operates within a supply voltage range of 3 V to 5.5 V. The device offers 5000 Vrms insulation voltage and supports a maximum output power of 400 mW. It exhibits a propagation delay of 60 ns and functions across a temperature range of -40°C to +105°C. Packaged in a 16-lead SOIC with 7.6 mm creepage distance, it eliminates the need for external isolation components.

Feature Summary

• Integrates an isolated DC/DC converter to provide regulated 5 V or 3.3 V outputs, removing the requirement for separate isolated power supplies.
• Utilizes magnetic coupling technology to achieve high-voltage isolation without optical degradation or electromagnetic interference susceptibility.
• Supports unidirectional signal transmission at speeds up to 25 Mb/s with low propagation delay for precise timing applications.

Applications

• Industrial automation systems requiring galvanic isolation between control logic and high-voltage power stages.
• Medical equipment needing reinforced isolation for patient-connected interfaces and safety compliance.
• Energy metering devices utilizing isolated communication buses for accurate data acquisition.
• Inverter drives and motor control circuits where noise immunity and compact form factors are critical.

Procurement Notes

Verify the specific suffix (e.g., ARWZ) against the manufacturer's current datasheet to ensure compatibility with required packaging and temperature grades. Confirm that the integrated DC/DC converter specifications meet the target application's power budget and regulatory isolation requirements before finalizing procurement decisions.

Selection Notes

Select this component when a compact solution combining signal isolation and isolated power generation is necessary. It is suitable for designs constrained by board space, as it replaces multiple discrete components. Ensure the input/output voltage levels align with the 3 V to 5.5 V operating range and that the 25 Mb/s data rate suffices for the communication protocol used.

Part Context

This part belongs to the ADUM6200 series of isoPower digital isolators. It shares architectural similarities with other members like the ADUM6200 and ADUM6202CRIZ but differs in package type and specific electrical characteristics such as pulse width distortion and operating current. The series is designed to simplify isolation design by integrating power conversion directly into the isolator package.

Replacement Considerations

Direct substitutes include ADUM6202ARWZ-RL for reel packaging variants. Cross-series replacements may involve ADUM6200ARWZ for single-channel needs or ADUM6202CRIZ for different creepage distances. Verify pinout compatibility and thermal performance when substituting.
