The ADM202EARWZ is a robust, high-speed, 2-channel RS-232/V.28 transceiver from Analog Devices Inc., designed to operate from a single 5V power supply. This interface IC is particularly suitable for situations where ±12V is not available, as it features an onboard charge pump that generates the necessary RS-232 voltage levels using only unipolar supply.

With a data rate of up to 200 kbps, the ADM202EARWZ is an excellent choice for applications that require fast data transmission while maintaining ESD protection of up to ±15kV on the RS-232 input/output lines. This level of protection ensures the device's reliability and longevity in harsh environments.

The ADM202EARWZ features two drivers and two receivers, making it ideal for full-duplex communication. It is compliant with the EIA-232E and CCITT V.28 specifications, and its design includes a shutdown feature that reduces the supply current to less than 1 µA, providing power-efficient operation for battery-powered applications.

The device comes in a wide-body, 16-lead SOIC (Small Outline Integrated Circuit) package, ensuring ease of integration into various designs. The ADM202EARWZ operates over the industrial temperature range of -40°C to +85°C, making it suitable for industrial environments where temperature extremes are common.

Typical applications for the ADM202EARWZ include:

• Portable Computing
• Low Power Modems
• Interface Translation
• Battery-Powered RS-232 Systems
• Handheld Equipment

With its combination of high-speed data transmission, robust ESD protection, and low-power shutdown mode, the ADM202EARWZ from Analog Devices Inc. is a reliable and efficient solution for enhancing serial communication in a variety of applications.
