GENERAL DESCRIPTION

The AD8016 high output current dual amplifier is designed for the line drive interface in Digital Subscriber Line systems such as ADSL, HDSL2, and proprietary xDSL systems. The drivers are capable, in full-bias operation, of providing 24.4 dBm output power into low resistance loads, enough to power a 20.4 dBm line, including hybrid insertion loss.
