Overview
The ADM213ARZ-REEL is a RS-232 transceiver integrated circuit produced by Analog Devices Inc. This component is part of the ADM2xx family, designed for EIA-232-E and V.28 communications interfaces. It is particularly useful in applications where ±12 V is not available, as it operates from a single 5 V supply. The ADM213 features internal charge pump voltage converters that generate the ±10 V required for RS-232 output levels from the 5 V input power.
