ADM3061EARMZ-R7

Overview

The ADM3061EARMZ-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 is housed in an 8-lead MSOP 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
• Supports connection of up to 128 transceivers on the bus

Applications

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

Procurement Notes

Verify the exact ordering suffix against the manufacturer's official documentation to confirm packaging type and grade. Ensure compatibility with required operating temperature ranges and interface standards before procurement. Cross-reference the datasheet specifications with system requirements to validate performance under expected electrical loads.

Selection Notes

Select this model for applications requiring half-duplex communication at 500 kbps over long cable runs. Verify that the system does not require the VIO logic supply pin, as this specific variant lacks it. Confirm that the 8-lead MSOP package meets the spatial constraints of the design. Check if PROFIBUS compliance at higher voltages is necessary for the application.

Part Context

This component belongs to the ADM306xE family of RS-485 transceivers from Analog Devices. The family includes variants supporting both 500 kbps and 50 Mbps data rates, as well as full-duplex configurations. The ADM3061E specifically targets low-speed, long-distance communication needs while maintaining high ESD robustness and thermal shutdown protection common to the series.

Replacement Considerations

ADM3061EARMZ is the tube-packaged equivalent of this reel-delivered part.
