ADM3061EBRMZ

Overview

The ADM3061EBRMZ 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 a maximum data rate of 500 kbps. The device features IEC 61000-4-2 electrostatic discharge (ESD) protection rated at ±12 kV for both contact and air discharge on the bus pins, along with HBM ratings exceeding ±30 kV. It utilizes an 8-lead MSOP package and functions across an extended temperature range from -40°C to +125°C. The component includes full receiver fail-safe capabilities and thermal shutdown protection.

Feature Summary

• IEC ESD protected bus pins withstand ±12 kV contact and air discharges without latch-up or damage
• Full hot swap support ensures glitch-free power-up and power-down operations
• Receiver provides fail-safe logic high output when inputs are shorted, open, or idle
• Thermal shutdown circuit prevents excessive power dissipation during fault conditions

Applications

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

Procurement Notes

Verify the specific ordering suffix against official documentation to confirm package type and temperature grade. Confirm that the procurement channel sources directly from authorized distributors to ensure component authenticity. Check for RoHS compliance status in the latest datasheet revision before finalizing orders.

Selection Notes

Select this model for applications requiring robust ESD protection on long cable runs where high-speed data rates are unnecessary. The 500 kbps data rate is optimized for minimizing common-mode emissions over extended distances. Ensure the system design accommodates the 8-lead MSOP package dimensions and thermal requirements for the intended operating environment.

Part Context

This component belongs to the ADM306xE family of RS-485 transceivers designed for harsh industrial environments. The family differentiates models based on duplex configuration, data speed, and the presence of a separate VIO logic supply pin. This specific part represents the low-speed, half-duplex variant without independent logic voltage control.

Replacement Considerations

Direct replacements within the same series include the ADM3061EARMZ (MSOP-8), ADM3061EBRZ (SOIC-8), and ADM3061EBRMZ-R7 (reel packaging). Verify pinout compatibility and thermal resistance specifications when substituting packages.
