Overview
The ADM3252EABCZ is a high-speed, 2.5 kV fully isolated, dual-channel RS-232/V.28 transceiver device manufactured by Analog Devices Inc. This component is designed to operate from a single 3.3 V or 5 V power supply, making it versatile for various applications. It incorporates Analog Devices' isoPower integrated, isolated dc-to-dc converter and chip scale transformer iCoupler technology, ensuring complete isolation of both power and data signals. This device is particularly suited for electrically harsh environments and applications where RS-232 cables are frequently connected and disconnected due to its high ESD protection and common-mode transient immunity.
