ADM3312EACPZ

ADM3312E is a 15kV ESD protected, 2.7V to 3.6V serial port transceiver with green idle. It 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 3V power supply. This dc-to-dc converter operates in green idle™ mode, where by the charge pump oscillator is gated on and off to maintain the output voltage at ±7.25V under varying load conditions. This minimizes the power consumption and makes ideal for battery-powered portable devices. It contains three drivers and three receivers and is intended for serial port applications. It is widely used in application such as mobile phone handsets/data cables, laptop and notebook computers, printers, peripherals, modems, PDAs/hand-held devices/palmtop computers etc.
