Product Overview: ADM487EARZ-REEL

The ADM487EARZ-REEL from Analog Devices Inc. is a high-performance, low-power transceiver designed for RS-485 and RS-422 communication protocols. This device is part of a family of transceivers that operate from a single 5 V power supply and is fully compliant with the EIA-485 and EIA-422 standards. The ADM487EARZ-REEL is available in a compact SOIC package and is part of a tape and reel package, making it ideal for automated manufacturing processes.

Key Features

• Integrated Protection: The device includes thermal shutdown and a current-limiting circuitry to protect against output short circuits and situations where bus contention may cause excessive power dissipation.
• Low Power Operation: It has a low quiescent current of 300 µA, which drops to less than 10 µA when in shutdown mode, making it suitable for power-sensitive applications.
• High Data Rates: The ADM487EARZ-REEL supports data rates up to 250 kbps, allowing for efficient communication in industrial environments.
• Extended Common-Mode Range: This transceiver can handle common-mode voltages from -7 V to +12 V, providing robust performance in electrically noisy environments or over long cable runs.
• Half-Duplex Operation: Designed for two-wire half-duplex communication, this transceiver allows for the transmission and reception of data over a single pair of wires.
• Thermal Shutdown and Short-Circuit Protection: Ensures the integrity of the transceiver in adverse conditions.

Applications

The ADM487EARZ-REEL is suitable for a wide range of applications in industrial, telecommunication, and commercial environments. It is commonly used in networked devices such as factory automation controls, HVAC systems, building automation, and any other systems that require a reliable RS-485 or RS-422 communications interface.
