ADM2682EBRIZ-RL7

Overview

The ADM2682EBRIZ-RL7 is a 5 kV rms signal and power isolated RS-485 transceiver featuring ±15 kV ESD protection. It integrates an isoPower DC-to-DC converter, eliminating external isolation components. The device supports data rates up to 16 Mbps with a supply voltage range of 3.0 V to 5.5 V. It includes current limiting and thermal shutdown for protection. The component operates within a temperature range of -40°C to +85°C and is housed in a 16-lead SOIC package.

Feature Summary

• Integrates a 5 kV rms isolated DC-to-DC converter for simultaneous signal and power isolation without external magnetics
• Provides robust ±15 kV electrostatic discharge protection on all ports
• Features fault-tolerant receiver inputs designed for open and shorted bus conditions

Applications

• Isolated RS-485/RS-422 communication interfaces
• Industrial fieldbus networks requiring galvanic isolation
• Multi-drop data transmission systems

Procurement Notes

Verify the specific suffix RL7 indicates tape and reel packaging when ordering. Confirm the operating voltage range matches the system requirements of 3.0 V to 5.5 V. Ensure the SOIC-16 footprint aligns with the printed circuit board layout. Check for RoHS compliance status if required by regulatory standards. Validate that the thermal management strategy accommodates the specified power dissipation limits.

Selection Notes

Select this component when high-speed isolation is required without external transformer complexity. It is suitable for applications demanding high common-mode transient immunity. Consider the integrated power supply feature to reduce bill of materials count. Evaluate the ±15 kV ESD rating for environments with significant static discharge risks. Ensure the 16 Mbps speed meets the network throughput requirements.
