Overview
The ADM560JR-REEL, produced by Analog Devices Inc., is an ultralow power RS-232 transceiver designed for use in notebook PCs and other power-sensitive applications. This device is part of the ADM560/ADM561 family, which operates from a single +3.3 V power supply and meets the EIA-232 standard. It features an on-board dc-to-dc converter that generates the necessary ±6.6 V from the input +3.3 V power supply, eliminating the need for dual ±5 V power supplies. This makes it highly suitable for battery-powered devices and other applications where power consumption is a critical factor.
