Working Principles

ADM207EARU is a full-duplex RS-232 transceiver that enables communication between two devices using serial data transmission. It operates by converting the logic level signals from the transmitting device into RS-232 compatible voltage levels and vice versa. The integrated charge pump generates the required voltage levels for RS-232 communication. The transceiver also features automatic power-down functionality to conserve power when not in use.
