Working Principles

ADM213AR operates as a line driver/receiver for RS-232 communication. It converts the logic level signals from the transmitting device into RS-232 compliant voltage levels for transmission over long distances. On the receiving end, it receives RS-232 signals and converts them back to logic level signals for further processing by the receiving device.

The IC utilizes internal charge pumps to generate the required positive and negative voltages for RS-232 signal levels. It also incorporates protection features such as thermal shutdown and short-circuit protection to ensure reliable operation.
