**The ADM202EARUZ-REEL: A High-Performance RS-232 Transceiver Solution for Modern Industrial Applications**

In the demanding landscape of modern industrial automation, process control, and instrumentation, reliable data communication is the backbone of operational integrity. The physical layer interface, often subjected to electrically harsh environments, must be robust and resilient. Addressing this critical need, the **ADM202EARUZ-REEL from Analog Devices** stands out as a premier RS-232 transceiver solution engineered to deliver uncompromising performance.

This integrated circuit is specifically designed to facilitate full-duplex RS-232 communication, translating signals between a device's logic-level UART and the higher-voltage RS-232 standard. What sets the ADM202EARUZ-REEL apart is its **inbuilt charge-pump circuitry**, which requires only a single +5V power supply to generate the necessary ±10V RS-232 transmission voltages. This eliminates the need for costly and cumbersome dual power supplies, simplifying system design and reducing both board space and overall bill-of-materials costs.

Engineered for reliability, the ADM202EARUZ-REEL is built to survive in tough conditions. It features **robust ESD protection of ±15 kV** on its transmitter outputs and receiver inputs (using the Human Body Model). This high level of protection is crucial in industrial settings where electrostatic discharge is a common threat, safeguarding the transceiver and the more sensitive components downstream from potential damage. Furthermore, its design ensures compliance with the stringent EIA-232E specifications, guaranteeing signal integrity over extended cable lengths.

The device's performance characteristics make it exceptionally suitable for a wide array of applications. It is ideal for interfacing with **Programmable Logic Controllers (PLCs)**, factory networking equipment, industrial computers, and diagnostic ports on heavy machinery. Its ability to operate at data rates up to 120 kbps ensures that it can handle the data throughput requirements of most modern industrial control systems efficiently.

Packaged in a compact 16-lead SOIC and supplied on a 7-inch reel, the **ADM202EARUZ-REEL is optimized for automated PCB assembly**, making it a perfect fit for high-volume manufacturing processes. Its combination of high noise immunity, low power consumption, and exceptional reliability establishes it as a cornerstone component for designers who cannot afford communication failures.

**ICGOODFIND**: The ADM202EARUZ-REEL is a superior RS-232 transceiver that masterfully balances performance, integration, and ruggedness. Its single-supply operation, high ESD protection, and industrial-grade durability make it an indispensable solution for ensuring dependable serial communication in the most challenging environments.
