Overview
The ADM213ARSZ is a 5V powered, CMOS RS-232 transceiver produced by Analog Devices Inc. This component is part of the ADM2xx family, designed for EIA-232-E and V.28 communications interfaces, particularly in applications where ±12 V is not available. It features a low power shutdown mode, making it suitable for battery-powered equipment. The ADM213ARSZ includes on-board dc-to-dc converters that generate the required ±10 V supply from a single 5 V input, using a switched capacitor technique.
