ADM3061EBRZ-R7

Overview

The ADM3061EBRZ-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 provides ±12 kV IEC contact discharge ESD protection on bus pins without latch-up or damage. It features a 1/4 unit load input impedance, allowing connection of up to 128 transceivers on the bus. The component includes full receiver fail-safe capabilities for short-circuit, open circuit, and bus idle conditions. It operates across an extended temperature range from -40°C to +125°C and is housed in an 8-lead narrow-body SOIC package.

Feature Summary

• IEC 61000-4-2 compliant electrostatic discharge protection on bus pins
• Full hot swap support with glitch-free power-up and power-down
• Receiver fail-safe design for shorted, open, or idle bus states
• Thermal shutdown circuitry 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 packaging format and reel specifications. Confirm that the procurement channel sources genuine components directly from Analog Devices or authorized distributors. Ensure the received part matches the exact model number and package type required for the application design.

Selection Notes

Select this component when a half-duplex RS-485 interface with high ESD immunity is required. The 500 kbps data rate is suitable for long cable runs where lower speed minimizes common-mode emissions. Verify compatibility with the system's logic voltage levels and ensure the thermal management strategy accommodates the specified junction temperature limits under expected load conditions.

Part Context

The ADM3061E belongs to the ADM306xE family of RS-485 transceivers designed for robust communication in noisy industrial environments. This series differentiates models based on duplex mode, data rate capability, and the presence of a separate VIO logic supply pin. The ADM3061E specifically targets applications requiring reliable half-duplex communication with integrated ESD protection.

Replacement Considerations

Direct replacements within the same family include the ADM3061EARMZ (MSOP package) or ADM3061EBR (tube packaging). Cross-manufacturer equivalents should be evaluated based on matching electrical parameters, pinout compatibility, and ESD protection ratings.
