GENERAL DESCRIPTION

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 5ꢀꢀ 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 −4ꢀ°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.
