ADM2565EBRNZ-RL7

Overview

The ADM2565EBRNZ-RL7 is a half-duplex RS-485 transceiver featuring integrated signal and power isolation rated at 3 kV RMS. It supports data rates up to 25 Mb/s with one driver and one receiver. 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 industrial temperature range of -40°C to +105°C. Packaged in a 28-pin SOIC, it includes an internal DC-DC converter for isolated power generation.

Feature Summary

• Integrates a high-voltage isolated DC-DC converter to generate internal power, eliminating the need for external isolated supplies.
• Provides robust electromagnetic interference immunity through digital isolation technology rated for 3 kV RMS.
• Features enhanced electrostatic discharge protection capable of withstanding ±15 kV according to IEC standards.

Applications

• Industrial automation systems requiring galvanic isolation
• Factory floor sensor networks and control loops
• Medical equipment with safety isolation requirements

Procurement Notes

Verify component authenticity by checking manufacturer markings against official datasheets. Confirm package integrity as moisture sensitivity is indicated. Ensure design compatibility with 3 V to 5.5 V logic levels. Validate isolation ratings match system safety requirements before integration.

Selection Notes

Select this component when high-speed communication up to 25 Mb/s is required alongside electrical isolation. It is suitable for applications needing integrated power isolation to simplify board layout. Consider thermal performance within the specified operating temperature range during design.

Part Context

This part belongs to the ADM256xE series of isolated RS-485 transceivers from Analog Devices. These devices are designed for harsh industrial environments where noise immunity and safety isolation are critical. The series offers various isolation ratings and data rate options to suit different application needs.

Replacement Considerations

Check ADM2565E variants for pin-compatible alternatives. Verify that substitute parts maintain the same 3 kV RMS isolation rating and 25 Mb/s data speed. Ensure the replacement supports the required SOIC-28 package and operating temperature range.
