ADM2482EBRWZ-REEL7

Overview

The ADM2482EBRWZ-REEL7 is a half-duplex RS-485 transceiver designed for industrial communication networks. It integrates an integrated isolated DC/DC converter to provide galvanic isolation between the logic and bus sides, ensuring safety in high-voltage environments. The device supports data rates up to 10 Mbps and operates with a single 3.3 V supply on both sides. Key electrical parameters include a minimum isolation voltage of 5 kVrms and a propagation delay of typically 15 ns. It features fail-safe receivers that ensure a high output state when inputs are open or shorted.

Feature Summary

• Integrated isolated DC/DC converter eliminates the need for external magnetic components
• Galvanic isolation protects sensitive logic circuits from high-voltage transients
• Fail-safe receiver design maintains a defined output state during idle conditions

Applications

• Industrial automation control systems
• Factory floor sensor networks
• Building management system communications

Procurement Notes

Verify the specific reel quantity and tape-and-reel packaging details against the manufacturer's current shipping specifications. Confirm that the EBRWZ suffix corresponds to the correct RoHS-compliant lead-free package variant required for your assembly process. Ensure compatibility with your board's thermal management strategy due to the integrated power converter.

Selection Notes

Select this component when high-density integration of isolation and power conversion is required for RS-485 interfaces. It is suitable for designs where space constraints prevent the use of discrete isolators and external transformers. Consider the 10 Mbps speed capability and the specific isolation voltage rating relative to the network's noise environment.

Part Context

This part belongs to Analog Devices' ADM248x family of isolated RS-485 transceivers. The family shares common architectural features such as integrated isolation barriers and fail-safe mechanisms. Variants within the series may differ in data rate, supply voltage, or package type, but maintain consistent functional behavior regarding isolation and bus driving capabilities.

Replacement Considerations

Direct replacements must match the integrated isolated DC/DC architecture and 5 kVrms isolation rating. Verify pinout compatibility with existing PCB layouts. Alternative parts from other manufacturers may require redesigning the isolation barrier and power supply sections if they lack integrated converters.
