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, a ther-  
mally enhanced 20-lead PSOP, and a 28-lead HTSSOP with  
an exposed leadframe (ePAD). 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  
33a and Figure 33b. Two digital bits (PWDN0, PWDN1) 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 imped-  
ance 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) terminal driver  
in ADSL, HDSL2, VDSL, and proprietary xDSL systems.
