ADM2795ETRWZ-EP

Overview

The ADM2795ETRWZ-EP is a military-grade, 5 kV rms isolated RS-485 transceiver featuring integrated DO-160G EMC protection and ±42 V AC/DC peak fault tolerance. It supports data rates up to 2.5 Mbps with a logic supply range of 1.7 V to 5.5 V and a bus supply range of 3 V to 5.5 V. The device provides high common-mode transient immunity exceeding 75 kV/μs and operates across an extended temperature range from −55°C to +125°C. Packaged in a 16-lead wide-body SOIC (RW-16), it includes certified safety approvals such as UL 1577 and IEC 60747-17 for reinforced insulation.

Feature Summary

• Integrates fully certified DO-160G Section 22 lightning protection and Section 25 ESD air discharge protection directly on the RS-485 bus pins.
• Features robust ±42 V AC/DC peak fault protection on the A and B bus pins to prevent damage from overvoltage conditions.
• Utilizes iCoupler technology to provide 5 kV rms signal isolation with a high common-mode transient immunity greater than 75 kV/μs.
• Designed for harsh environments with military qualification supporting defense and aerospace applications under AQEC standards.

Applications

• Military and aerospace avionics systems including sensors, actuators, and engine control interfaces
• Avionics communication networks requiring compliance with DO-160G environmental testing standards
• Industrial RS-485 networks exposed to severe electromagnetic interference and lightning-induced transients

Procurement Notes

Verify that the specific ordering suffix matches the required packaging format, as the base model is available in both tube and reel configurations. Confirm the presence of the EP designation to ensure the component meets the enhanced product baseline and controlled manufacturing requirements necessary for qualified defense and aerospace deployments.

Selection Notes

Select this component when system design requires integrated DO-160G certification without external surge suppression components. Ensure the application utilizes a 1.7 V to 5.5 V logic supply and a 3 V to 5.5 V bus supply to maintain full TIA/EIA RS-485/RS-422 compliance. Verify that the 16-lead wide-body SOIC package dimensions fit the PCB layout constraints.

Part Context

This part belongs to the ADM2795E-EP series, representing Analog Devices' enhanced product line for ruggedized isolated communications. It shares functional similarities with non-isolated variants like the ADM3095E but adds critical galvanic isolation and aviation-specific transient protection capabilities required for MILA environments.

Replacement Considerations

Direct replacements include the ADM2795ETRWZ-EP-R7 for reel-packaged inventory or the standard ADM2795ETRWZ if military qualification is not mandatory. Non-isolated alternatives like the ADM3095EBRZ lack the required isolation barrier and DO-160G certification.
