PRODUCT DESCRIPTION
The AD8011 is a very low power, high speed amplifier designed
to operate on +5 V or ± 5 V supplies. With wide bandwidth,
low distortion, and low power, this device is ideal as a general-
purpose amplifier. It also can be used to replace high speed
amplifiers consuming more power. The AD8011 is a current feed-
back amplifier and features gain flatness of 0.1 dB to 25 MHz
while offering differential gain and phase error of 0.02% and 0.06°
on a single 5 V supply. This makes the AD8011 ideal for profes-
sional video electronics such as cameras, video switchers, or any
high speed portable equipment. Additionally, the AD8011’s low
distortion and fast settling make it ideal for buffering high speed
8-, 10-, and 12-bit A-to-D converters.
The AD8011 offers very low power of 1 mA maximum and can
run on single 5 V to 12 V supplies. All this is offered in a small
8-lead PDIP or 8-lead SOIC package. These features fit well with
portable and battery-powered applications where size and power
are critical.
The AD8011 is available in the industrial temperature range of
–40°C to +85°C.

NOTES
1 Stresses above those listed under Absolute Maximum Ratings may cause perma-
nent damage to the device. This is a stress rating only; functional operation of the
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.
2 Specification is for device in free air:
8-Lead PDIP Package: JA = 90°C/W
8-Lead SOIC Package: JA = 155°C/W

MAXIMUM POWER DISSIPATION
The maximum power that can be safely dissipated by the AD8011
is limited by the associated rise in junction temperature. The
maximum safe junction temperature for plastic encapsulated
devices is determined by the glass transition temperature of the
plastic, approximately 150°C. Exceeding this limit temporarily
may cause a shift in parametric performance 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 AD8011 is internally short-circuit protected, this may
not be sufficient to guarantee that the maximum junction tem-
perature is not exceeded under all conditions. To ensure proper
operation, it is necessary to observe the maximum power derating
curves (shown in Figure 3).

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
AD8011 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.
