Overview
The ADM2209EARUZ from Analog Devices Inc. is a highly integrated, dual RS-232 port transceiver designed for robust serial communication applications. This device features six drivers and ten receivers, fully compliant with EIA-232 and V.28 specifications. It operates with a single +12 V power supply and includes an on-board dc-to-dc converter to generate the necessary -12 V power rail, eliminating the need for a separate negative power supply. The ADM2209EARUZ is engineered to operate in harsh electrical environments and is compliant with EU directives on EMC (89/336/EEC), ensuring both low emissions and high immunity to electromagnetic interference.
