GENERAL DESCRIPTION
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
well-suited for applications where power consumption is
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
operate in two states. When the DCO pin is tied to VCC, the
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
rated for operation over the extended industrial temperature
range of −40°C to +85°C.
