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.
