PRODUCT 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.

AD8016ARE
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.
