GENERAL DESCRIPTION
The ADA4410-6 is a comprehensive integrated filtering solution
that is carefully designed to give designers the flexibility to
easily filter and drive many types of video signals, including
high definition video. In the RGB/component channels, the
cutoff frequencies of the sixth-order filters can be selected by
two logic pins to obtain four filter combinations that are tuned
for RGB, high definition, and standard definition video. Cutoff
frequencies range from 9 MHz to 36 MHz.
The ADA4410-6 also provides filtering for the legacy standard
S-video and composite video signals. With a differential gain of
0.11% and a differential phase of 0.25, the ADA4410-6 is an
excellent choice for any composite video (CV) application.
The ADA4410-6 offers gain and output offset voltage
adjustments. With a single logic pin, the gain of the part can be
selected to be 2 or 4. Output offset voltage is continuously
adjustable over an input-referred range of 500 mV by applying
a differential voltage to an independent offset control input.

Figure 1.
The ADA4410-6 offers 2:1 multiplexers on its inputs that can be
used in applications where multiple sources of video exist.
The ADA4410-6 can operate on a single +5 V supply as well as
5 V supplies. Single-supply operation is ideal for applications
where power consumption is critical. The disable feature allows
for further power conservation by reducing the supply current
to typically 15 A when a particular device is not in use.
Dual-supply operation is best for applications where the
negative-going excursions of the signal must swing at or below
ground while maintaining excellent video performance. The
output buffers have the ability to drive two 75 doubly
terminated cables that are either dc- or ac-coupled.
The ADA4410-6 is available in a 32-lead LFCSP and operates in
the extended industrial temperature range of -40C to +85C.
