Overview
The ADM213AR, produced by Analog Devices Inc., is a member of the ADM2xx family of RS-232 line drivers and receivers. This component is designed to meet EIA-232-E and V.28 communications interface specifications, particularly in applications where ±12 V is not available. It operates from a single 5 V supply and features on-board dc-to-dc converters that generate the required ±10 V for RS-232 output levels. The ADM213AR is well-suited for battery-powered equipment due to its low power shutdown mode, which reduces power dissipation to less than 5 μW.
