ADM3061EBRMZ-R7

Overview

The ADM3061EBRMZ-R7 is a half-duplex RS-485 transceiver manufactured by Analog Devices Inc. It operates within a supply voltage range of 3.0 V to 5.5 V and supports data rates up to 500 kbps. The device features IEC 61000-4-2 electrostatic discharge protection rated at ±12 kV for both contact and air discharge, alongside HBM ratings of ±30 kV. It utilizes an 8-lead MSOP package and functions across an extended temperature range from -40°C to +125°C. Key electrical characteristics include a maximum no-load supply current of 7.5 mA and driver output short-circuit protection.

Feature Summary

• IEC 61000-4-2 ESD protection on bus pins withstands ±12 kV contact and air discharges without latch-up or damage
• Full hot swap capability ensures glitch-free power-up and power-down operations
• Integrated thermal shutdown circuit prevents excessive power dissipation during fault conditions
• Receiver fail-safe guarantees a logic high output when inputs are shorted, open, or idle

Applications

• Industrial fieldbuses
• Process control systems
• Building automation networks
• PROFIBUS networks
• Motor control servo drives and encoders

Procurement Notes

Verify the component against official Analog Devices documentation to confirm the specific suffix matches the required reel packaging format. Ensure the ordering part number aligns with the intended operating temperature grade and package variant. Cross-reference technical specifications directly with the manufacturer's datasheet to validate performance parameters before integration into production designs.

Selection Notes

Select this model for applications requiring robust ESD protection and reliable communication over long cable runs due to its 500 kbps data rate. Confirm compatibility with the system's power supply voltage range between 3.0 V and 5.5 V. Verify that the 8-lead MSOP package dimensions fit the available PCB space constraints. Ensure the design accounts for the thermal resistance characteristics associated with the selected package type.

Part Context

This component belongs to the ADM306xE family of RS-485 transceivers designed for harsh industrial environments. The series offers various duplex options and data rate capabilities, ranging from 500 kbps to 50 Mbps. The ADM3061E specifically provides half-duplex functionality optimized for standard RS-485 bus topologies requiring high noise immunity and extensive node connectivity.

Replacement Considerations

Direct replacements within the same family include other ADM3061E variants with different package options such as SOIC_N. For higher speed requirements, consider the ADM3065E which maintains similar pinouts but supports 50 Mbps data rates. Verify that any substitute maintains the required IEC ESD protection levels and thermal performance characteristics.
