ADM3063EBRZ

Overview

The ADM3063EBRZ-R7 is a full-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 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 receiver fail-safe capabilities for short-circuit, open circuit, and bus idle conditions. It is housed in a 14-lead narrow-body SOIC package and operates across an extended temperature range from -40°C to +125°C.

Feature Summary

• Full hot swap support with glitch-free power-up and power-down functionality
• Integrated thermal shutdown circuit prevents excessive power dissipation during fault conditions
• PROFIBUS compliant operation at supply voltages greater than or equal to 4.5 V

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 manufacturer documentation to confirm packaging details such as reel quantity. Confirm that the component grade matches the required operating temperature range for the intended application environment. Cross-reference the datasheet revision to ensure all electrical specifications align with current design requirements before finalizing procurement orders.

Selection Notes

Select this model when full-duplex communication is required alongside high ESD tolerance. The 500 kbps rate suits long cable runs where slew rate limiting minimizes common-mode emissions. Ensure the system logic interface does not require a separate VIO pin, as this variant lacks that feature compared to other models in the series. Verify package availability matches the PCB footprint constraints.

Part Context

This component belongs to the ADM306xE family of RS-485 transceivers designed for robust industrial communication. The family differentiates models based on duplex mode, data rate, and logic supply options. This specific part represents the full-duplex, low-speed option within the 14-lead SOIC package category, providing a balance of speed and noise immunity for standard industrial bus applications.

Replacement Considerations

ADM3064EBRZ offers similar full-duplex performance but includes a VIO logic supply pin for flexible digital interfaces.
