ADM3061EARZ-R7

Overview

The ADM3061EARZ-R7 is a half-duplex RS-485 transceiver manufactured by Analog Devices Inc. It operates within a VCC supply 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 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 narrow-body SOIC 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 61000-4-2 Level 4 electrostatic discharge protection on bus pins without latch-up or damage
• Full hot swap support allowing glitch-free power-up and power-down operations
• Receiver fail-safe design ensuring logic high output during short-circuit, open circuit, or bus idle 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. Ensure compatibility with system voltage requirements and interface standards before integration. Cross-reference manufacturer datasheets for accurate pin configurations and electrical specifications.

Selection Notes

Select this model for applications requiring robust ESD protection and reliable communication over long cable runs at moderate speeds. Consider the 8-lead SOIC package for space-constrained designs. Verify that the half-duplex architecture aligns with the bidirectional data flow requirements of the target network topology.

Part Context
