The ADA4417-3 is a low cost, fully integrated, video
reconstruction filter specifically designed for consumer high
definition video. With 1 dB frequency flatness out to 38 MHz,
and 44 dB of rejection at 75 MHz, the ADA4417-3 can handle
the most demanding HD video applications.
The ADA4417-3 operates on a single 3.3 V to 5 V supply. It is
ell-suited for applications where power consumption is
w
critical. A disable feature allows for further power conservation
by reducing the supply current to 10 µA (typical) when the
device is not in use. With rail-to-rail output, it can be efficiently
used on a 3.3 V supply, while providing the user with a 2 V p-p
output. The buffers can drive two 75 Ω terminated loads, either
dc- or ac-coupled.

The ADA4417-3 also has an output dc offset function that can
o
perate in two states. When the DCO pin is tied to V
video signal at the output is offset by 200 mV. When the DCO
pin is tied to ground, the output dc level follows the input level.
The ADA4417-3 is available in a 10-lead MSOP package and is
ra
ted for operation over the extended industrial temperature
range of −40°C to +85°C.

Maximum Power Dissipation
The maximum safe power dissipation in the ADA4417-3
package is limited by the associated rise in junction temperature
(T
) on the die. At approximately 150°C, which is the glass
J
transition temperature, the plastic changes its properties. Even
temporarily exceeding this temperature limit can change the
stresses that the package exerts on the die, permanently shifting
the parametric performance of the ADA4417-3. Exceeding a
junction temperature of 175°C for an extended period can
result in changes in the silicon devices potentially causing
failure.

ESD 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 this product 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.
