Overview
The ADM3310EARU, produced by Analog Devices Inc., is a three-driver/five-receiver serial port transceiver designed to meet the EIA-232 standard. This device operates from a single power supply ranging from 2.7 V to 3.6 V, making it suitable for a variety of applications requiring serial communication. The ADM3310EARU features an on-board charge pump dc-to-dc converter, which eliminates the need for dual power supplies and generates the necessary positive and negative voltages internally. This design ensures minimal power consumption and is particularly beneficial for battery-powered and portable devices.
