ADM3312EARU

15千伏ESD保护， 2.7 V至3.6 V串行端口收发器与绿色Idle⑩ 15 kV ESD Protected, 2.7 V to 3.6 V Serial Port Transceivers with Green Idle⑩

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.
