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.

The AD8016 is available in a low cost 24-lead SOIC and a thermally enhanced 20-lead PSOP. Operating from ± 12 V supplies, the AD8016 requires only 1.5 W of total power

dissipation (refer to the Power Dissipation section for details) while driving 20.4 dBm of power downstream using the xDSL hybrid in Figure 44a and Figure 44b. Two digital bits (PDWN0, PDWN1) allow the driver to be capable of full performance, an output “keep-alive state,” or two intermediate bias states. The “keep-alive” state biases the output transistors enough to provide a low impedance at the amplifier outputs for back termination. The low power dissipation, high output current, high output voltage swing, flexible power-down and robust thermal packaging enable the AD8016 to be used as the Central Office (CO) or Customer Premise Equipment (CPE) terminal driver in ADSL, HDSL2, VDSL and proprietary xDSL systems.
