ADM2687EBRIZ

Overview

The ADM2687EBRIZ is a 5 kV rms signal and power isolated RS-485 transceiver featuring ±15 kV ESD protection. It integrates a 3-channel digital isolator, a differential line driver, a receiver, and an isoPower DC-to-DC converter in a 16-pin SOIC package. The device supports data rates up to 500 kbps with supply voltages of 3.3 V or 5 V. Operating temperatures range from -40°C to +85°C. Propagation delays are specified at 63 ns for transmission and 64 ns for reception.

Feature Summary

• Integrates a 5 kV rms isolated DC-to-DC converter eliminating external isolation components
• Provides robust ±15 kV electrostatic discharge protection on bus pins
• Includes current limiting and thermal shutdown for output short-circuit protection

Applications

• Isolated RS-485/RS-422 industrial communication interfaces
• Multipoint data transmission systems
• Industrial field networks requiring galvanic isolation

Procurement Notes

Verify the specific suffix BRIZ indicates tape and reel packaging when sourcing. Confirm active status directly with Analog Devices as distribution availability varies. Ensure the procurement channel provides original manufacturer documentation to validate authenticity and traceability for industrial applications.

Selection Notes

Select this component for designs requiring integrated power isolation without external magnetics. Compare against the ADM2682E if higher data rates up to 16 Mbps are necessary. Verify that the 500 kbps speed meets system timing requirements. Check pin compatibility with existing SOIC-16 footprints during PCB layout.

Part Context

This part belongs to the ADM268xE family of isolated transceivers. It shares architectural similarities with the ADM2682E but offers lower maximum data rates. The series utilizes iCoupler technology for signal isolation and isoPower for energy transfer across the isolation barrier within a single compact package.

Replacement Considerations

The ADM2682EBRIZ serves as a high-speed alternative within the same family. Both parts share identical pinouts and isolation specifications. Designers should verify that the increased speed capabilities of the ADM2682E do not introduce signal integrity issues in existing layouts.
