PRODUCT DESCRIPTION

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 SFDR at 100 kHz on 12 V, outstanding performance for any xDSL CPE application.
