ADM4851ARZ - Low Power, 5 V, RS-485/RS-422 Transceiver by Analog Devices Inc.

The ADM4851ARZ is a high-performance, single transceiver chip designed by Analog Devices Inc. for bidirectional communication on RS-485 or RS-422 networks. This integrated circuit is engineered to operate in a wide range of industrial, commercial, and telecommunication applications where robustness and reliability are critical.

Constructed for low power consumption, the ADM4851ARZ operates from a single 5 V power supply, making it an ideal choice for energy-sensitive designs. Its low power requirements do not compromise its performance, as it is capable of data rates up to 5 Mbps, allowing for efficient data transfer over long distances up to 4000 feet (approximately 1200 meters).

Key Features:

• Interface Type: RS-485, RS-422
• Data Rate: Up to 5 Mbps
• Operating Voltage: 5 V
• Half-Duplex: Transceiver facilitates bidirectional communication on a single pair of wires.
• Low Power Consumption: Ideal for power-sensitive applications.
• Extended Temperature Range: Operable between -40°C to +85°C, suitable for harsh environments.
• Robust ESD Protection: Withstands ±15kV Human Body Model (HBM).
• Package: SOIC-8 (Small Outline Integrated Circuit)
• True Fail-Safe Receiver: Ensures a logic-high receiver output when the inputs are open or shorted, or when they are connected to a terminated transmission line with all drivers disabled.

The device also features thermal shutdown and current limiting to protect against output driver overload, enhancing the durability and longevity of the transceiver. Furthermore, the ADM4851ARZ is designed with an 8-lead SOIC package, providing a compact footprint suitable for space-constrained applications.

With its combination of high-speed communication, low power operation, and robust protection features, the ADM4851ARZ from Analog Devices Inc. is an excellent choice for designers who need a reliable transceiver for RS-485 or RS-422 networks in industrial automation, HVAC systems, and other applications requiring a dependable data communication interface.
