ADM2587EBRWZ

Overview

The ADM2587EBRWZ is a fully integrated signal and power isolated RS-485/RS-422 transceiver from Analog Devices. It features magnetic coupling technology for galvanic isolation with a rating of 2500 Vrms. The device supports data rates up to 500 kbps and includes an integrated DC-to-DC converter for isolated power supply. It operates within a voltage range of 3 V to 5.5 V and provides 15 kV ESD protection. The component is housed in a 20-SOIC package and functions as a unidirectional, two-channel interface suitable for industrial applications.

Feature Summary

• Integrates signal and power isolation via magnetic coupling technology
• Includes built-in DC-to-DC converter for isolated power generation
• Provides high electromagnetic immunity with 25 kV/µs common-mode transient rejection
• Offers robust electrostatic discharge protection rated at 15 kV

Applications

• Industrial process control systems requiring isolated communication
• Factory automation networks utilizing RS-485 or RS-422 protocols
• Power monitoring equipment needing galvanic separation between circuits
• Medical devices requiring safe isolation barriers for patient connections

Procurement Notes

Verify the specific suffix (e.g., REEL7 vs. standard tube) against your manufacturing requirements, as packaging formats differ significantly between reel and tube options. Confirm that the 20-SOIC footprint matches your PCB design constraints. Ensure compliance with RoHS directives and check moisture sensitivity levels for proper storage and reflow soldering profiles during assembly.

Selection Notes

Choose this component when both signal integrity and isolated power delivery are required in a single package. It is suitable for designs needing high common-mode transient immunity in noisy environments. Consider the 500 kbps speed limit and 2500 Vrms isolation barrier when defining system safety and performance requirements relative to other interface standards.

Part Context

This part belongs to the ADM2587E series of IsoPower digital isolators. It combines the functionality of an RS-485/RS-422 transceiver with a magnetic coupler-based isolator and a DC-to-DC converter. This integration reduces component count and board space compared to discrete solutions using separate isolators and isolated power supplies.
