GENERAL DESCRIPTION
●The ADM33xxE line of driver/receiver products is designed to fully meet the EIA-232 standard while operating with a single 2.7 V to 3.6 V power supply. The devices feature an on-board
●charge pump dc-to-dc converter, eliminating the need for dual power supplies. This dc-to-dc converter contains a voltage tripler and a voltage inverter that internally generates positive
●and negative supplies from the input 3 V power supply. The dc-to-dc converter operates in Green Idle mode, whereby the charge pump oscillator is gated ON and OFF to maintain the output
●voltage at ±7.25 V under varying load conditions. This minimizes the power consumption and makes these products ideal for battery-powered portable devices.
