ADM3315EARUZ

ADM3315E is a 15kV ESD protected, 2.7 V to 3.6V serial port transceivers 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. 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 ±7.25V under varying load conditions. This minimizes the power consumption and makes ideal for battery-powered portable devices. It is a low current version of the ADM3312E, with a 22Kohm receiver input resistance that reduces the drive requirements of the DTE. 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.
