ADM3251EARWZ-REEL by Analog Devices Inc.

The ADM3251EARWZ-REEL is a high-performance, isolated single-channel RS-232/V.28 transceiver component manufactured by Analog Devices Inc. This device is part of the REEL series, which indicates that it is typically supplied in tape and reel packaging, suitable for automated assembly processes. The ADM3251EARWZ-REEL is designed to provide robust communication with a focus on reliability and safety, making it an ideal choice for industrial, medical, and other applications where isolation is crucial.

This transceiver incorporates Analog Devices Inc.'s iCoupler® technology to facilitate isolation between the logic side and the RS-232 bus. The isolation provided by the ADM3251EARWZ-REEL helps to protect sensitive circuitry from noise, spikes, and surges commonly found in industrial environments. It also helps in breaking ground loops and allows for the safe interfacing between different voltage domains.

The ADM3251EARWZ-REEL operates from a single 5V power supply and features a fully integrated ESD protection, withstanding up to ±15 kV on the RS-232 transceiver input/output lines. This ensures the longevity and durability of the device in harsh electrical environments. The transceiver is capable of data rates up to 250 kbps, making it suitable for most serial communication applications.

Key features of the ADM3251EARWZ-REEL include:

• 2.5 kV RMS isolation for 1 minute as per UL 1577
• RS-232 data rate up to 250 kbps
• Single 5V power supply operation
• Integrated ESD protection up to ±15 kV
• Thermal shutdown protection
• Low power consumption
• Small 20-lead wide-body SOIC package

Applications for the ADM3251EARWZ-REEL are diverse and include industrial control and automation, isolated RS-232 interfaces, data acquisition systems, and medical equipment where patient safety and equipment reliability are of paramount importance. Its robust design and high isolation capabilities make the ADM3251EARWZ-REEL a trusted component for engineers looking to implement isolated serial communications with confidence.

Analog Devices Inc. is known for its high-quality and innovative components, and the ADM3251EARWZ-REEL is no exception, providing reliable performance and ease of integration for a wide range of isolated communication needs.
