PRODUCT DESCRIPTION
The AD8116 is a high speed 16 × 16 video crosspoint switch
matrix. It offers a –3 dB signal bandwidth greater than 200 MHz
and channel switch times of 60 ns with 0.1% settling. With –70dB
of crosstalk and –1 dB of isolation (@ 5 MHz), the AD8116
is useful in many high speed applications. The differential gain
and differential phase errors of better than 0.01% and 0.01°,
respectively, along with 0.1 dB flatness out to 60 MHz make the
AD8116 ideal for video signal switching.
The AD8116 includes output buffers that can be placed into a
high impedance state for paralleling crosspoint outputs so that
off channels do not load the output bus. It operates on voltage

supplies of ± 5 V while consuming only 90 mA of idle current.
The channel switching is performed via a serial digital control
that can accommodate “daisy chaining” of several devices.
The AD8116 is packaged in a 128-lead LQFP package occupy-
ing only 0.36 square inches, and is specified over the commer-
cial temperature range of 0°C to 70°C.

NOTES
1Stresses 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.
2Specification is for device in free air (TA = 25°C):
128-lead plastic LQFP (ST): θJA = 37°C/W.
MAXIMUM POWER DISSIPATION
The maximum power that can be safely dissipated by the
AD8116 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
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.
Exceeding a junction temperature of 175°C for an extended
period can result in device failure.
While the AD8116 is internally short circuit protected, this may
not be sufficient to guarantee that the maximum junction temp-
erature (150°C) 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 AD8116 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.
