Overview
The ADM213ARS-REEL is a member of the ADM2xx family of RS-232 and V.28 interface devices produced by Analog Devices Inc. This component is designed to operate from a single 5 V power supply, making it suitable for applications where ±12 V is not available. It features on-board dc-to-dc converters that generate the ±10 V required for RS-232 output levels from the 5 V input power.
