Overview
The ADM3312EARUZ is a serial port transceiver produced by Analog Devices Inc. This device is part of the ADM3307E/ADM3310E/ADM3311E/ADM3312E/ADM3315E family, designed to fully meet the EIA-232 standard. It operates with a single 2.7 V to 3.6 V power supply, utilizing an on-board charge pump dc-to-dc converter to generate the necessary positive and negative supplies. This converter operates in Green Idle™ mode, minimizing power consumption and making it ideal for battery-powered portable devices.
