ADM3061EARZ

Overview

The ADM3061EARZ 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 ±12 kV IEC contact discharge ESD protection on the bus pins without latch-up or damage. It includes full receiver fail-safe capabilities for short-circuit, open circuit, and bus idle conditions. The component is housed in an 8-lead SOIC package and supports operation across extended temperature ranges.

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 for short-circuit, open circuit, and bus idle states
• Thermal shutdown circuitry prevents excessive power dissipation

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 provides genuine components from Analog Devices Inc. Check datasheet specifications for thermal resistance values relevant to your PCB layout requirements before finalizing orders.

Selection Notes

Select this model for applications requiring 500 kbps data transmission over long cable runs. Ensure the system design accommodates the 8-lead narrow-body SOIC package dimensions. Verify that the operating environment falls within the specified electrical parameters and temperature limits defined in the datasheet.

Part Context

This component belongs to the ADM306xE family of RS-485 transceivers designed for robust industrial communication. The series offers various duplex modes and data rate options, including high-speed 50 Mbps variants. The ADM3061E specifically targets cost-sensitive applications needing reliable half-duplex communication with integrated ESD protection.

Replacement Considerations

Direct replacements include other models within the ADM306xE family such as the ADM3062E or ADM3063E, provided pin compatibility and functional requirements match. Verify package footprint and logic supply configurations when substituting.
