Overview
The ADM3307EARUZ-REEL, produced by Analog Devices Inc., is a highly integrated RS-232 transceiver designed to meet the EIA-232 standard. This device operates with a single 2.7 V to 3.6 V power supply and features an on-board charge pump dc-to-dc converter, eliminating the need for dual power supplies. The converter generates positive and negative supplies from the input power, making it ideal for battery-powered portable devices. The ADM3307EARUZ-REEL is particularly suited for harsh electrical environments due to its robust ESD protection and low power consumption in shutdown mode.
