Overview
The ADM560JRZ-REEL, produced by Analog Devices Inc., is a highly integrated RS-232 transceiver designed to meet the EIA-232 standard. This device is optimized for low power consumption and operates from a single +3.3 V power supply, making it ideal for power-sensitive applications such as notebook PCs and battery-powered devices. The ADM560 features four drivers and five receivers, and it includes an on-board dc-to-dc converter that eliminates the need for dual ±5 V power supplies.
