Overview
The ADM213EARZ is an RS-232 transceiver produced by Analog Devices Inc., designed to address various serial communication interface needs. This component is part of the ADM2xx family, which is intended for EIA-232-E and V.28 communications interfaces, particularly in scenarios where ±12 V supplies are not available. The ADM213EARZ operates from a single 5 V supply and includes internal charge pump voltage converters that generate the necessary ±10 V for RS-232 output levels.
