ADM2565EBRNZ

Overview

The ADM2565EBRNZ is a half-duplex RS-485 transceiver featuring 3 kV RMS signal and power isolation. It supports data rates up to 25 Mb/s with a common-mode transient immunity of 250 kV/µs. The device operates on a supply voltage range of 3 V to 5.5 V, drawing 28 mA of quiescent current. It provides 15 kV IEC ESD protection and functions within an operating temperature range of -40°C to +105°C. Packaged in a 28-pin SOIC, it integrates isolated drivers and receivers for robust industrial communication.

Feature Summary

• Integrates 3 kV RMS digital isolation for both signal and power domains
• Provides high-speed data transmission capability up to 25 Mb/s
• Features enhanced electromagnetic interference immunity via 250 kV/µs CMTI
• Includes built-in 15 kV IEC standard electrostatic discharge protection

Applications

• Industrial automation control systems
• Factory floor sensor networks
• Building automation interfaces
• Energy metering equipment

Procurement Notes

Verify the specific suffix 'BRNZ' to confirm RoHS compliance and lead-free status. Confirm package type is SOIC-28. Check Analog Devices official documentation for current lifecycle status as availability may be limited. Ensure input voltage levels match the 1.7 V to 5.5 V specification for logic compatibility.

Selection Notes

Select this component when galvanic isolation between microcontroller and bus is required. Choose over non-isolated RS-485 parts if ground potential differences exist. Consider the 25 Mb/s rate for high-bandwidth needs. Verify thermal performance within the -40°C to +105°C range for harsh environments.

Part Context

This part belongs to the ADM256x family of isolated RS-485 transceivers from Analog Devices. It shares architectural similarities with the ADM2561 but offers specific isolation ratings. The series targets applications requiring reliable communication in electrically noisy industrial settings where safety isolation is mandated.

Replacement Considerations

Check Analog Devices datasheets for direct pin-compatible alternatives within the ADM256x series. Verify isolation voltage ratings and data speed requirements against existing designs before substitution.
