ADA4411-3
Figure 1.
The ADA4411-3 is a comprehensive filtering solution designed
to give designers the flexibility to easily filter and drive various
video signals, including high definition video. Cutoff frequen-
cies of the sixth-order video filters range from 9 MHz to
36 MHz and can be selected by two logic pins to obtain four
filter combinations that are tuned for RGB, high definition, and
standard definition video signals. The ADA4411-3 has a rail-
to-rail output that can swing 4.5 V p-p on a single 5 V supply.
The ADA4411-3 can operate on a single +5 V supply as well as
on ±5 V supplies. Single-supply operation is ideal in
applications where power consumption is critical. The disable
feature allows for further power conservation by reducing the
supply current to typically 15 μA when a particular device is not
in use.
Dual-supply operation is best for applications where the
negative-going video signal excursions must swing at or
below ground while maintaining excellent video performance.
The output buffers have the ability to drive two 75 Ω doubly
terminated cables that are either dc-coupled or ac-coupled.
The ADA4411-3 offers gain and voltage offset adjustments.
With a single logic pin, the throughput filter gain can be
selected to be ×2 or ×4. Output voltage offset is continuously
adjustable over an input-referred range of ±500 mV by applying
a differential voltage to an independent offset control input.
The ADA4411-3 is available in the 24-lead, wide body
QSOP and is rated for operation over the extended
industrial temperature range of 40°C to +85°C.
The ADA4411-3 offers 2:1 multiplexers on all of its video
inputs, which are useful in applications where filtering is
required for multiple sources of video signals.
