Overview
The ADM3202ARWZ-REEL, manufactured by Analog Devices Inc., is a high-speed, 2-channel RS-232/V.28 interface transceiver. This device operates from a single 3.3 V power supply, making it ideal for low-power applications. It is particularly suited for battery-powered portable instruments due to its low power consumption and shutdown facility. The ADM3202ARWZ is available in a 16-lead SOIC package and is designed to meet EIA-232E and CCITT V.28 specifications.
