ADM2795ETRWZ-EP-R7

Overview

The ADM2795ETRWZ-EP-R7 is a robust, 5 kV rms isolated RS-485/RS-422 transceiver featuring ±42 V AC/DC peak fault protection on bus pins. It integrates iCoupler technology for signal isolation and certified DO-160G EMC protection. The device supports data rates up to 2.5 Mbps with a logic supply range of 1.7 V to 5.5 V (VDD1) and a bus supply range of 3 V to 5.5 V (VDD2). It provides high common-mode transient immunity exceeding 75 kV/μs and operates over an extended temperature range of −55°C to +125°C.

Feature Summary

• DO-160G Section 22 lightning protection certification for Waveform 3, Waveform 4/Waveform 1, and Waveform 5A at Level 4.
• Integrated safety approvals including UL 1577, DIN EN IEC 60747-17, and IEC/EN/CSA 60950-1.
• Enhanced product features supporting defense and aerospace applications under the AQEC standard.
• Glitch-free power-up and power-down capabilities enabling hot swap functionality.

Applications

• Military and aerospace avionics for sensors, actuators, and engine control
• Harsh environment communication systems requiring high noise immunity
• Avionics networks subject to severe electromagnetic interference

Procurement Notes

Verify that the specific suffix -R7 corresponds to the reel packaging option containing 400 units per 7-inch reel. Confirm the -EP designation indicates the enhanced product baseline required for military and aerospace qualification standards. Ensure the ordering documentation explicitly references the AQEC standard compliance for defense applications.

Selection Notes

Select this component when operating environments demand certified DO-160G lightning protection and high common-mode transient immunity. The wide logic supply range down to 1.7 V facilitates interfacing with low-voltage microcontrollers. Verify that the system can accommodate the required external current-limiting resistors if testing or operating against GND2 for specific DO-160G waveforms.

Part Context

This part belongs to the ADM2795E-EP family, which is specifically engineered for defense and aerospace sectors. Unlike standard commercial variants, the EP series maintains a controlled manufacturing baseline at a single assembly site. It includes enhanced product change notifications and available qualification data to meet rigorous industry reliability requirements.

Replacement Considerations

The ADM2795ETRWZ-EP is the tube version of this component. Standard ADM2795EBRWZ-RL7 lacks the EP military/aerospace enhancements and DO-160G certifications. Substitution requires verifying that the application does not mandate the specific AQEC standard controls provided by the EP variant.
