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.

FREQUENCY (kHz)
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.

The maximum power that can be safely dissipated by the AD8016
is limited by the associated rise in junction temperature. The
maximum safe junction temperature for plastic encapsulated
device is determined by the glass transition temperature of the
plastic, approximately 150°C. Temporarily exceeding this limit
may cause a shift in parametric performance due to a change in
the stresses exerted on the die by the package.
The output stage of the AD8016 is designed for maximum load
current capability. As a result, shorting the output to common
can cause the AD8016 to source or sink 2000 mA. To ensure
proper operation, it is necessary to observe the maximum power
derating curves. Direct connection of the output to either power
supply rail can destroy the device.

CAUTION
ESD (electrostatic discharge) sensitive device. Electrostatic charges as high as 4000 V readily
accumulate on the human body and test equipment and can discharge without detection.
Although the AD8016 features proprietary ESD protection circuitry, permanent damage may
occur on devices subjected to high energy electrostatic discharges. Therefore, proper ESD
precautions are recommended to avoid performance degradation or loss of functionality.
