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 GBR/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 GBR, high definition, and standard definition video. Cutoff
frequencies range from 36 MHz to 9 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 ADA441-6 offers gain and output offset voltage
adjustments. The gain of the part can be ×2 or ×4, and the
output offset voltage is continuously adjustable up to ±2 V
by applying a differential voltage to an independent offset
control input.

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. A disable feature allows
for further power conservation.

Dual-supply operation is for applications where the negative­going 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 Ω terminated loads that
are either dc- or ac-coupled.

The ADA4410-6 is available in a 32-lead LFCSP and operates in
the commercial temperature range of −40°C to +85°C.

The ADA4410-6 offers 2:1 multiplexers on its inputs that can be
used in applications where multiple sources of video exist.
