ADM2490EBRWZ

Overview

The ADM2490EBRWZ is a high-speed, full-duplex RS-485 transceiver featuring iCoupler isolation technology. It operates within a supply voltage range of 2.7 V to 5.5 V and supports data rates up to 16 Mb/s. The device provides 8 kV ESD protection on the bus pins and offers a common-mode transient immunity (CMTI) of 25 kV/µs. It is housed in a 16-pin SOIC package and functions across an operating temperature range of -40°C to +105°C.

Feature Summary

• Integrates digital isolation using iCoupler technology for galvanic separation between logic and bus sides.
• Supports full-duplex communication with independent transmit and receive channels.
• Provides robust electrostatic discharge protection directly on the differential bus lines.

Applications

• Industrial automation networks requiring high-speed serial communication
• Building automation systems utilizing RS-485 protocols
• Process control environments with significant ground potential differences

Procurement Notes

Verify the specific suffix against official Analog Devices documentation to confirm packaging configuration. Confirm that the procurement channel sources genuine components from authorized distributors to ensure compliance with RoHS standards and operational reliability specifications.

Selection Notes

Select this component when full-duplex operation is required alongside high-speed data transmission capabilities. The integrated isolation eliminates the need for external isolators, simplifying board layout while maintaining signal integrity in electrically noisy industrial environments.

Part Context

This part belongs to the ADM2490E series of isolated transceivers. It shares the core functional architecture with other members of the family but differs in packaging and reel specifications. The device complements half-duplex variants like the ADM2486 by providing simultaneous bidirectional data flow.

Replacement Considerations

ADM2490EBRWZ-REEL7 serves as a verified alternative packaging option for the same functional device. Ensure pinout compatibility and isolation voltage ratings match when substituting with other RS-485 transceivers from different manufacturers.
