ADUM6201ARWZ-RL

Overview

The ADUM6201ARWZ-RL is a general-purpose digital isolator from Analog Devices, featuring two independent channels with an integrated DC/DC converter. It operates within a supply voltage range of 3 V to 5.5 V and supports data rates up to 25 Mb/s. The device provides 5000 Vrms isolation voltage and utilizes magnetic coupling technology. Key electrical parameters include a propagation delay of 60 ns, typical rise and fall times of 2.5 ns, and a pulse width distortion of 1000 ns. It functions reliably across an operating temperature range of -40°C to +105°C and is housed in a 16-SOIC package.

Feature Summary

• Integrates an on-chip DC/DC converter to generate isolated power for the secondary side, eliminating the need for external isolated power supplies.
• Employs iCoupler magnetic coupling technology to provide high-speed signal transmission with robust common-mode transient immunity.
• Offers dual-channel unidirectional isolation with a wide operating temperature range suitable for industrial environments.

Applications

• Industrial automation systems requiring galvanic isolation between microcontrollers and peripheral devices.
• Medical equipment needing reliable signal isolation with high creepage distances.
• Power metering applications involving isolated communication interfaces such as RS-485 or CAN bus.

Procurement Notes

Verify the specific suffix 'ARWZ-RL' to confirm the reel packaging format and automotive-grade qualification status. Ensure compatibility with existing PCB footprints for the 16-SOIC package. Confirm that the integrated DC/DC converter requirements align with the target application's power budget and noise sensitivity constraints before finalizing procurement.

Selection Notes

Select this component when a compact solution with integrated isolated power generation is required for bidirectional or unidirectional data links. Compare against non-isolated alternatives if cost is critical, but prioritize this part for high-voltage isolation needs. Consider the 25 Mb/s data rate limit and ensure it meets the system timing requirements. Evaluate thermal performance given the internal DC/DC converter operation at higher temperatures.

Part Context

This part belongs to the ADUM6201 series of digital isolators designed for high-reliability applications. It represents a shift towards integrating power conversion directly into the isolation barrier, simplifying board design. The series is widely used in industries demanding strict safety standards and long-term reliability, leveraging Analog Devices' proprietary iCoupler technology for superior performance compared to traditional optical or transformer-based isolators.

Replacement Considerations

Direct substitutes may include other ADUM6201 variants with different packaging options, such as ADUM6201ARWZ for tube packaging. Cross-family comparisons should consider parts like the ADuM41xx series if integrated power is not required, though pinouts and features will differ significantly. Verify functional equivalence regarding isolation voltage and data rate when selecting alternative components.
