ADM2587EBRWZ-REEL7

Overview

The ADM2587EBRWZ-REEL7 is a digital isolator transceiver from the ADM2587E series, manufactured by Analog Devices Inc. It supports full and half duplex RS-485 communication at data rates up to 500 kbps. The device features magnetic coupling isolation with an insulation voltage of 2500 Vrms and provides 15 kV ESD protection. It operates on a single power supply ranging from 3 V to 5.5 V, drawing a typical operating current of 125 mA. The component exhibits a propagation delay of 200 ns and functions within a temperature range of -40°C to +85°C. It is housed in a 20-SOIC package and is supplied in reel packaging.

Feature Summary

• Integrates signal and power isolation using magnetic coupling technology for robust noise immunity.
• Provides high common-mode transient immunity to maintain signal integrity in electrically noisy environments.
• Includes integrated ESD protection rated at 15 kV to safeguard against electrostatic discharge events.

Applications

• Industrial automation systems requiring isolated RS-485 communication
• Building automation networks utilizing half or full duplex protocols
• Process control instrumentation with galvanic isolation needs

Procurement Notes

Verify the specific suffix REEL7 confirms the reel packaging format required for your assembly line. Confirm the SOIC-20 package dimensions match your PCB footprint design. Ensure the 3 V to 5.5 V supply range aligns with your system voltage rails. Check humidity sensitivity classifications for proper storage and handling procedures during manufacturing.

Selection Notes

Select this component when both signal and power isolation are required within a single RS-485 interface solution. The 2500 Vrms isolation rating suits applications demanding significant galvanic separation between domains. Consider the 500 kbps speed limit if higher throughput is necessary, as faster alternatives exist. The unidirectional channel configuration defines the input-output relationship for circuit design.

Part Context

This part belongs to the ADM2587E family of IsoPower digital isolators. These devices combine RS-485 transceivers with iCoupler magnetic isolation technology. The family offers integrated power conversion capabilities, reducing the need for external isolated DC/DC converters. This integration simplifies board layout and improves overall system reliability compared to discrete solutions.

Replacement Considerations

The non-reel version ADM2587EBRWZ serves as a direct functional substitute available in tube packaging. Both parts share identical electrical characteristics and pinouts. Verify that the change in packaging format does not impact automated pick-and-place equipment settings.
