ADM2682EBRIZ

Overview

The ADM2682EBRIZ is a single-channel, full-duplex RS-422/RS-485 transceiver featuring integrated 5 kV rms signal and power isolation. It supports data rates up to 16 Mbps with ±15 kV ESD protection on I/O pins and 25 kV/µs common-mode transient immunity. The device operates from a 3 V to 5.5 V supply within the -40°C to +85°C temperature range. Packaged in a 16-pin SOIC, it includes an internal isolated DC-to-DC converter, eliminating external isolation components.

Feature Summary

• Integrates iCoupler technology for combined signal isolation and isolated power generation
• Provides robust electromagnetic interference rejection via high common-mode transient immunity
• Includes built-in thermal shutdown and short-circuit current limiting for fault protection

Applications

• Isolated RS-485 and RS-422 industrial communication interfaces
• Multi-drop fieldbus networks requiring galvanic isolation
• Data acquisition systems with noisy electrical environments

Procurement Notes

Verify component authenticity through authorized Analog Devices distributors or certified partners. Confirm package marking matches SOIC-16 specifications and date codes align with production timelines. Request official datasheets and compliance certificates during procurement to ensure adherence to RoHS standards and regulatory requirements for industrial safety certifications.

Selection Notes

Select this component when designing systems requiring simultaneous signal and power isolation without external magnetics. It is suitable for applications needing high-speed data transmission over long distances with significant ground potential differences. Consider the 16-pin footprint and thermal characteristics for PCB layout optimization in dense industrial control panels.

Part Context

Part of the ADM2682E series, which provides complete isolation solutions for serial communication buses. This specific variant utilizes tape-and-reel packaging (indicated by suffixes in related part numbers like ADM2682EBRIZ-RL7) for automated assembly processes, distinguishing it from tube-packaged equivalents while maintaining identical electrical performance and isolation ratings.
