Overview
The ADM560JRS, produced by Analog Devices Inc., is an ultralow power, +3.3 V RS-232 serial port driver/receiver designed for notebook PC and other power-sensitive applications. This device meets the EIA-232 standard and operates with a single +3.3 V power supply, eliminating the need for dual ±5 V power supplies. It features an on-board dc-to-dc converter that includes a voltage doubler and a voltage inverter, generating ±6.6 V from the input +3.3 V power supply. The ADM560JRS is part of the ADM560/ADM561 family, which is known for its low power consumption and suitability for battery-powered devices.
