ADM3062EARMZ-R7

Overview

The ADM3062EARMZ-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 a dedicated VIO logic supply pin, allowing flexible digital interface operation down to 1.62 V. It provides IEC 61000-4-2 electrostatic discharge protection rated at ±12 kV for both contact and air discharge on the bus pins. The component is housed in a 10-lead MSOP package with dimensions of 3 mm × 3 mm.

Feature Summary

• IEC 61000-4-2 ESD protection on bus pins
• Flexible VIO logic supply option
• Full hot swap support

Applications

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

Procurement Notes

Verify the specific ordering suffix against official manufacturer documentation to confirm package type and tape-and-reel configuration. Ensure that the VIO pin voltage requirements align with the target system's logic levels before finalizing procurement decisions.

Selection Notes

Select this model when a low-speed 500 kbps data rate is sufficient for long cable runs. The inclusion of the VIO pin makes it suitable for systems requiring independent logic voltage domains. Confirm that the 10-lead MSOP package meets the spatial constraints of the printed circuit board design.

Part Context

This component belongs to the ADM306xE family of RS-485 transceivers designed for robust communication in noisy industrial environments. The series offers various speed grades and duplex options, with the ADM3062E specifically providing half-duplex functionality at 500 kbps with integrated ESD protection capabilities.

FAQ

Does the ADM3062E support PROFIBUS?

Yes, the ADM3062E is fully compliant with the PROFIBUS standard when the VCC supply voltage is greater than or equal to 4.5 V.

What is the purpose of the VIO pin?

The VIO pin serves as a separate logic supply input, enabling a flexible digital interface that can operate independently from the main VCC power supply down to 1.62 V.

How does the device handle bus contention?

The transceiver includes a thermal shutdown circuit that detects significant temperature increases during fault conditions, such as output shorting, and forces the driver output into a high impedance state.
