ADM2763EBRWZ

Overview

The ADM2763EBRWZ is a full-duplex RS-485 transceiver featuring 5.7 kV RMS signal isolation and ±15 kV IEC ESD protection on bus pins. It operates at a maximum data rate of 500 kbps with a primary supply voltage range of 1.7 V to 5.5 V and an isolated secondary supply range of 3.0 V to 5.5 V. The device includes a receiver cable inversion feature for correcting reversed A/B connections while maintaining fail-safe performance. It supports up to 192 bus nodes, offers high common-mode transient immunity exceeding 250 kV/µs, and functions within a temperature range of -40°C to +125°C in a 16-lead wide-body SOIC package.

Feature Summary

• Integrated receiver cable inversion pin corrects reversed A/B bus connections without losing fail-safe operation
• Robust electrostatic discharge protection on all RS-485 bus pins meeting IEC 61000-4-2 standards
• High differential output voltage optimized for long-distance communication and PROFIBUS compliance
• Low radiated emissions design passes EN 55032 Class B testing on standard two-layer PCBs

Applications

• Solar inverters
• Electrical test and measurement equipment
• Heating, ventilation, and air conditioning (HVAC) networks
• Industrial field buses
• Building automation systems

Procurement Notes

Verify the specific ordering suffix against official Analog Devices documentation to confirm package type and reel specifications. Confirm that the component meets required safety certifications such as UL 1577 or pending DIN EN IEC 60747-17 approvals for your specific application environment. Ensure proper handling precautions are taken due to the sensitivity of the isolation barrier.

Selection Notes

Select this component when high working voltage insulation and robust ESD protection are critical requirements. The ADM2763E is specifically designed for applications requiring correction of reversed cabling on the A and B lines. Verify that the system power supplies align with the specified ranges: 1.7 V to 5.5 V for the primary side and 3.0 V to 5.5 V for the isolated side.

Part Context

This part belongs to the ADM2761E/ADM2763E family of 5.7 kV RMS isolated RS-485 transceivers. The ADM2763E variant is distinguished by its receiver cable inversion capability, whereas the ADM2761E lacks this specific pin. Both devices share identical isolation ratings, ESD protection levels, and electrical characteristics for general RS-485 communication.

Replacement Considerations

The ADM2761EBRWZ serves as a direct functional substitute if the receiver cable inversion feature is not required. Other ADM276x series devices may offer different isolation voltages or duplex configurations but require verification of pin compatibility and electrical parameters.
