3.3 V to +12 V DSL Line Drive Amplifier with Power Down

The AD8391 consists of two parallel, low cost xDSL line drive amplifiers capable of driving low distortion signals while running on both +3 V to +12 V single-supply or equivalent dual-supply rails. It is primarily intended for use in single-supply xDSL systems where low power is essential, such as line powered and battery backup systems. Each amplifier output drives more than 250 mA of current while maintaining -82 dBc of distortion at 100 kHz on +12 V, outstanding performance for any xDSL CPE application.

* High Output Voltage and Current Drive: 250mA Minimum Output Drive Current, 10Vp-p Output Voltage, RL=21 ohms

* Low Power Operation: +3.3V to +12V Power Supply Range, 19mA(typ) Supply Current, 1-pin logic controlled Stand-by, Shutdown

* Low Distortion: -94dBc SFDR @ 100kHz into 21 ohms, 8Vp-p
