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.

The AD8016 is available in a low cost 24-lead SO-Batwing,
a thermally enhanced 20-lead PSOP3, and a 28-lead TSSOP-EP
with an exposed lead frame (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 perfor-
mance, 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) terminal driver
in ADSL, HDSL2, VDSL, and proprietary xDSL systems.
