ADM2567EBRNZ-RL7

Overview

The ADM2567EBRNZ-RL7 is a 3 kV RMS signal and power isolated RS-485 transceiver manufactured by Analog Devices Inc. It integrates an integrated DC-DC converter to provide galvanic isolation for both data and power domains. The device supports half-duplex communication with a data rate of up to 25 Mbps. It features ±15 kV IEC ESD protection on the bus pins, ensuring robust performance in harsh industrial environments. The component operates within a supply voltage range of 3 V to 5.5 V and functions across an extended temperature range from -40°C to +105°C.

Feature Summary

• Integrates an isolated DC-DC converter to eliminate the need for external magnetic components
• Provides 3 kV RMS galvanic isolation between signal and power domains
• Features high electromagnetic immunity with ±15 kV IEC ESD protection on bus lines

Applications

• Industrial automation systems requiring isolated RS-485 communication
• Factory automation networks with long cable runs
• Process control instrumentation with ground potential differences

Procurement Notes

Verify the specific suffix RL7 indicates reel packaging when sourcing. Confirm the 3 kV RMS isolation rating matches system requirements rather than higher-rated variants like the ADM286x series. Ensure compatibility with the SOIC-28 package dimensions during PCB layout. Check for moisture sensitivity level (MSL) handling requirements prior to assembly.

Selection Notes

Select this component when a compact solution with integrated power isolation is required for RS-485 networks. It is suitable for designs needing 25 Mbps throughput without external isolators. Compare against non-integrated isolator solutions to evaluate board space savings. Consider the 3 kV RMS rating sufficient for most industrial applications where 5.7 kV is not mandated.

Part Context

This part belongs to the ADM256xE family of isolated RS-485 transceivers from Analog Devices. It shares architectural similarities with the ADM2561E but offers higher data rates. The family is designed to simplify isolated interface design by combining the transceiver and DC-DC converter in a single package.

Replacement Considerations

The ADM2567EBRNZ is the base part number for the tube variant, while RL7 denotes the reel packaging. Direct functional substitutes include other ADM256xE series devices with matching isolation ratings.
