PRODUCT DESCRIPTION
The AD8010 is a low power, high current amplifier capable of
delivering a minimum load drive of 175 mA. Signal performance
such as 0.02% and 0.03° differential gain and phase error is
maintained while driving eight 75
Ω
back terminated video lines.
The current feedback amplifier features gain flatness to 60 MHz
and –3 dB (G = +1) signal bandwidth of 230 MHz and only
requires a typical of 15.5 mA supply current from
±5
V supplies.
These features make the AD8010 an ideal component for Video
Distribution Amplifiers or as the drive amplifier within high data
rate Digital Subscriber Line (VDSL and xDSL) systems.
The AD8010 is an ideal component choice for any application
that needs a driver that will maintain signal quality when driving
low impedance loads.
The AD8010 is offered in three package options: an 8-lead DIP,
16-lead wide body SOIC and a low thermal resistance 8-lead
SOIC, and operates over the industrial temperature range of
–40°C to +85°C.

Stresses above those listed under Absolute Maximum Ratings may cause perma-

device at these or any other conditions above those indicated in the operational
section of this specification is not implied. Exposure to absolute maximum rating
conditions for extended periods may affect device reliability.

MAXIMUM POWER DISSIPATION – Watts
The maximum power that can be safely dissipated by the
AD8010 is limited by the associated rise in junction tempera-
ture. The maximum safe junction temperature for plastic
encapsulated devices is determined by the glass transition tem-
perature of the plastic, approximately +150°C. Temporarily
exceeding this limit may cause a shift in parametric perfor-
mance due to a change in the stresses exerted on the die by the
package. Exceeding a junction temperature of +175°C for an
extended period can result in device failure.
While the AD8010 is internally short circuit protected, this
may not be sufficient to guarantee that the maximum junction
temperature (+150°C) is not exceeded under all conditions. To
ensure proper operation, it is necessary to observe the maximum
power derating curves.

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 AD8010 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.
