ADM3062EBRMZ-R7

Overview

The ADM3062EBRMZ-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 the digital interface to operate at voltages as low as 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 an exposed pad and is designed for operation across an extended temperature range from -40°C to +125°C.

Feature Summary

• Supports flexible digital interfaces through a separate VIO logic supply pin capable of operating down to 1.62 V.
• Provides robust bus protection against high-energy electrostatic discharge events without latch-up or damage.
• Enables connection of up to 128 transceivers on a single bus line due to 1/4 unit load input impedance.

Applications

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

Procurement Notes

Verify that the ordering suffix matches the required tape and reel packaging configuration. Confirm the specific grade (A or B) corresponds to the necessary operating temperature range for the target application environment. Ensure the 10-lead MSOP footprint aligns with the intended PCB layout constraints.

Selection Notes

Select this model when a half-duplex RS-485 interface is required alongside a low-voltage logic domain below 3.0 V. The integrated ESD protection eliminates the need for external transient suppression components on the bus lines. Consider thermal dissipation requirements if operating near the upper limits of the junction temperature rating.

Part Context

This component belongs to the ADM306xE family of RS-485 transceivers. It shares core specifications with the ADM3061E but adds the VIO logic supply capability found in higher-tier models like the ADM3066E. The R7 suffix indicates the device is supplied in a tape and reel format suitable for automated surface-mount assembly processes.
