ADM3307 Datasheet PDF

●The ADM3307EACPZ is a Serial Port Transceiver designed to fully meet the EIA-232 standard while operating with a single 2.7 to 3.6V power supply. The device features 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 this ideal for battery-powered portable devices. This device is suitable for operation in harsh electrical environments and contains ESD protection up to ±15kV on its RS-232 lines. The ADM3307E contains ESD protection up to ±15kV on all I/O lines. A shutdown facility that reduces the power consumption to 66nW is also provided.
