ADM2487EBRWZ-REEL7

Overview

The ADM2487EBRWZ-REEL7 is an isolated RS-485/RS-422 transceiver manufactured by Analog Devices Inc. It operates on a single 5 V supply and supports data rates up to 500 kbps. The device provides galvanic isolation with a voltage rating of 2500 Vrms and common mode transient immunity of 25 kV/µs. It features a SOIC-16 package, unidirectional channel configuration, and operates within a temperature range of -40°C to +85°C.

Feature Summary

• Integrated oscillator driver for external transformer coupling
• Configurable as half-duplex or full-duplex transceiver
• High common mode transient immunity

Applications

• Industrial automation systems
• Process control networks
• Building automation interfaces

Procurement Notes

Verify the specific suffix REEL7 indicates tape-and-reel packaging when ordering. Confirm the 500 kbps speed variant matches system requirements, distinguishing it from higher-speed models in the same family. Ensure the SOIC-16 footprint aligns with PCB layout constraints.

Selection Notes

Select this component for applications requiring robust galvanic isolation in noisy industrial environments. The integrated oscillator driver simplifies design by reducing external component count compared to discrete isolator solutions. Verify that the 500 kbps throughput meets the network latency requirements.

Part Context

This part belongs to the ADM2487E series of isolated transceivers. It utilizes capacitive isolation technology to separate the logic side from the bus side. The device is designed to replace traditional optocoupler-based designs with improved performance and smaller form factors.

Replacement Considerations

ADM2487EBRWZ is the tube version of this reel-packaged component. Other ADM248x variants may offer different data rates or isolation voltages but require pinout verification.
