GENERAL DESCRIPTION

The ADA4412-3 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 ADA4412-3 has a rail-to-

rail output that can swing 4.5 V p-p on a single 5 V supply.

The ADA4412-3 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 1ꢀ 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 ADA4412-3 includes an output offset voltage adjustment

feature. 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 ADA4412-3 is available in a 2ꢀ-lead QSOP and is rated for

operation over the extended industrial temperature range of

−4ꢀ°C to +85°C.
