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.  
the xDSL hybrid in Figure 35 and Figure 36. 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 impedance at the amplifier outputs  
for back termination.  
The AD8016 is available in a low cost 24-lead SOIC_W_BAT  
and a 28-lead TSSOP_EP with an exposed lead frame (ePAD).  
Operating from 12 ꢀ 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 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, ꢀDSL, and proprietary  
xDSL systems.
