Overview
Ultralow Power +3.
3 V, RS-232 Notebook PC Serial Port Drivers/Receivers ADM560/ADM561 FEATURES RS-232 compatible Operates with 3 V or 5 V logic Ultralow power CMOS: 1.
3 mA operation Low power shutdown: 0.
2 μA Suitable for serial port mice 116 kbps data rate 1 μF charge pump capacitors Single +3 V to +3.
6 V power supply Two receivers active in shutdown (ADM560) APPLICATIONS Notebook computers Peripherals Modems Printers Battery-operated equipment GENERAL DESCRIPTION The ADM560/ADM561 are four driver/five receiver interface devices designed to meet the EIA-232 standard and operate with a single +3.
3 V power supply.
The devices feature an on-board dc-to-dc converter, eliminating the need for dual ±5 V power supplies.
This dc-to-dc converter contains a voltage doubler and voltage inverter, both of which internally generate ±6.
6 V from the input +3.
3 V power supply.
The ADM560 and the ADM561 consume only 5 mW making them ideally suited for battery and other power-sensitive applications...
