ADM2763EBRWZ-RL7

Overview

The ADM2763EBRWZ-RL7 is a 5.7 kV RMS signal isolated, full-duplex RS-485 transceiver featuring ±15 kV IEC ESD protection on bus pins. It supports a maximum data rate of 500 kbps and operates over a temperature range of −40°C to +125°C. The primary VDD1 supply accepts 1.7 V to 5.5 V, while the isolated VDD2 supply requires 3.0 V to 5.5 V. Quiescent currents are typically 1 mA (VDD1) and 5 mA (VDD2). Common-mode transient immunity exceeds 250 kV/µs. The device utilizes a 16-lead wide-body SOIC package with 8.2 mm creepage and clearance.

Feature Summary

• Integrated receiver cable inversion pin for correcting reversed A/B bus connections
• Robust system-level EMC immunity compliant with IEC 61000-4-x standards
• High differential output voltage suitable for PROFIBUS nodes at 5 V operation
• Passes EN 55032 Class B radiated emissions 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 component authenticity through authorized Analog Devices distributors or certified partners. Confirm that the delivered parts match the specific ADM2763EBRWZ-RL7 designation and packaging format. Ensure storage conditions comply with moisture sensitivity level requirements prior to soldering. Review the latest datasheet revision for any updates to safety certifications or electrical parameters before finalizing procurement orders.

Selection Notes

Select this model when high working voltage isolation up to 1500 VDC is required alongside robust ESD protection. The ADM2763E variant is specifically chosen over the ADM2761E if hardware correction for reversed bus wiring is necessary. Ensure the application environment stays within the specified -40°C to +125°C operating range. Verify that the isolated side power supply can accommodate the 3.0 V to 5.5 V input requirement for proper functionality.

Part Context

This component belongs to the ADM2761E/ADM2763E family of isolated RS-485 transceivers manufactured by Analog Devices. It shares core specifications with the ADM2761E but adds a dedicated receiver cable inversion feature. The RL7 suffix indicates reel packaging for automated surface-mount assembly processes.

Replacement Considerations

The ADM2761E serves as a direct functional substitute if cable inversion logic is not required in the design. Other ADM276x series devices may offer different isolation ratings or duplex configurations.
