Overview
The ADM3315EACPZ-REEL7 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 and features an on-board charge pump dc-to-dc converter, eliminating the need for dual power supplies. This converter internally generates positive and negative supplies from the input power supply, operating in Green Idle™ mode to minimize power consumption.
