Additional Details

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.
