ADM2563EBRNZ

Overview

The ADM2563EBRNZ is a full-duplex RS-485 transceiver manufactured by Analog Devices Inc., housed in a 28-pin SOIC package. It provides 3 kV RMS signal and power isolation with integrated DC-DC conversion, supporting data rates up to 500 kb/s. The device operates on a supply voltage range of 3 V to 5.5 V and draws 28 mA of operating current. It features robust ESD protection rated at 15 kV IEC standard and functions reliably within an industrial temperature range from -40°C to +105°C.

Feature Summary

• Integrates magnetic coupling for simultaneous signal and power isolation across the barrier
• Includes built-in DC-DC converter to generate isolated power without external components
• Provides high electromagnetic interference immunity through differential signaling

Applications

• Industrial automation control systems requiring galvanic isolation
• Factory floor sensor networks and actuator interfaces
• Building automation and HVAC communication links

Procurement Notes

Verify the specific ordering suffix against official Analog Devices documentation to confirm package type and tape-and-reel specifications. Confirm RoHS compliance status and moisture sensitivity level requirements prior to integration into manufacturing processes.

Selection Notes

Select this component when both signal integrity and isolated power delivery are required in a single package. Compare against non-isolated alternatives if ground potential differences are absent. Ensure the 3 kV RMS isolation rating meets the safety standards of the target application environment.

Part Context

This part belongs to the ADM256xE series of isolated RS-485 transceivers. It shares the SOIC-28 footprint with variants like the ADM2561EBRNZ but differs in duplex capability and isolation architecture. The series targets harsh industrial environments where electrical noise and ground loops are prevalent concerns.

Replacement Considerations

ADM2561EBRNZ offers similar isolation but may differ in duplex configuration or internal circuitry. Verify pin compatibility and functional equivalence before substitution.
