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.
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 μA 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 Ω 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 −40°C to +85°C.
