ADM2490EBRWZ-REEL7

Overview

The ADM2490EBRWZ-REEL7 is a high-speed, full-duplex RS-485 transceiver featuring iCoupler digital isolation technology. It operates from a single 5V supply and supports data rates up to 16 Mbps. The device provides 5 kV RMS isolation between the logic and bus sides, ensuring robust performance in noisy industrial environments. It integrates ESD protection on the RS-485 A and B pins and includes fault protection capabilities.

Feature Summary

• Integrates iCoupler digital isolation for galvanic separation of logic and bus domains
• Supports high-speed full-duplex communication with data rates up to 16 Mbps
• Provides integrated ESD and fault protection on differential bus lines

Applications

• Industrial automation systems requiring isolated RS-485 connectivity
• Factory floor networks with high electromagnetic interference
• Building automation and control systems

Procurement Notes

Verify the specific suffix REEL7 confirms tape-and-reel packaging when ordering. Confirm the 5V operating voltage requirement matches your system design. Ensure compatibility with the SOIC-16 package dimensions for PCB layout. Check current availability status as distribution may vary by region.

Selection Notes

Select this component when high-speed full-duplex RS-485 communication requires strong galvanic isolation. It is suitable for applications needing 5 kV isolation without external magnetics. Consider the 5V supply constraint and 16 Mbps speed limit against other interface requirements.

Part Context

This part belongs to the ADM2490E family of isolated RS-485 transceivers. It utilizes Analog Devices' iCoupler technology to replace traditional magnetic isolators. The series is designed for reliable data transmission in electrically noisy industrial settings.

Replacement Considerations

Direct substitutes include the ADM2490EBRWZ (non-reel) or ADM2490EBRZ-RL7. Verify pinout and isolation ratings match before substitution.
