ApplicationsThe AD811 is also excellent for pulsed applications where tran-
sient response is critical. It can achieve a maximum slew rate of
greater than 2500 V/ms with a settling time of less than 25 ns to
0.1% on a 2 volt step and 65 ns to 0.01% on a 10 volt step.
The AD811 is ideal as an ADC or DAC buffer in data acquisi-
tion systems due to its low distortion up to 10 MHz and its wide
unity gain bandwidth. Because the AD811 is a current feedback
amplifier, this bandwidth can be maintained over a wide range
of gains. The AD811 also offers low voltage and current noise of
1.9 nV/√Hz and 20 pA/√Hz, respectively, and excellent dc accu-
racy for wide dynamic range applications.
PRODUCT DESCRIPTIONThe AD811 is a wideband current-feedback operational ampli-
fier, optimized for broadcast quality video systems. The –3 dB
bandwidth of 120 MHz at a gain of +2 and differential gain and
phase of 0.01% and 0.01° (RL = 150 W) make the AD811 an
excellent choice for all video systems. The AD811 is designed to
meet a stringent 0.1 dB gain flatness specification to a band-
width of 35 MHz (G = +2) in addition to the low differential
gain and phase errors. This performance is achieved whether
driving one or two back terminated 75 W cables, with a low
power supply current of 16.5 mA. Furthermore, the AD811 is
specified over a power supply range of –4.5 V to –18 V.

MAXIMUM POWER DISSIPATIONThe maximum power that can be safely dissipated by the
AD811 is limited by the associated rise in junction temperature.
For the plastic packages, the maximum safe junction tempera-
ture is +145°C. For the cerdip and LCC packages, the maxi-
mum junction temperature is +175°C. If these maximums are
exceeded momentarily, proper circuit operation will be restored
as soon as the die temperature is reduced. Leaving the device in
the “overheated” condition for an extended period can result in
device burnout. To ensure proper operation, it is important to
observe the derating curves in Figures 17 and 18.
While the AD811 is internally short circuit protected, this may
not be sufficient to guarantee that the maximum junction tem-
perature is not exceeded under all conditions. One important
example is when the amplifier is driving a reverse terminated
75 W cable and the cable’s far end is shorted to a power supply.
With power supplies of –12 volts (or less) at an ambient tem-
perature of +25°C or less, if the cable is shorted to a supply rail,
then the amplifier will not be destroyed, even if this condition
persists for an extended period.
ESD SUSCEPTIBILITYESD (electrostatic discharge) sensitive device. Electrostatic
charges as high as 4000 volts, which readily accumulate on the
human body and on test equipment, can discharge without
detection. Although the AD811 features proprietary ESD pro-
tection circuitry, permanent damage may still occur on these
devices if they are subjected to high energy electrostatic dis-
charges. Therefore, proper ESD precautions are recommended
to avoid any performance degradation or loss of functionality.
