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 frequencies of the 6th order video filters range from 9 MHz to 36 MHz. The filters are tuned for RGB, high definition, and standard definition video signals.
The ADA4411-3 offers gain and voltage offset adjustments. With a single logic pin, the throughput filter gain can be selected to be x2 or x4. 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 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.
The ADA4411-3 can operate on a single +5 V supply as well as ±5 V supplies. Single-supply operation is ideal in applications where power consumption is critical. The disable feature allows for further power conservation by greatly reducing the supply current when a particular device is not in use.
The output buffers have the ability to drive two 75 Ω terminated loads that are either dc-coupled or ac-coupled.
The ADA4411-3 is available in the 24-lead, wide body QSOP and is rated for operation over the industrial temperature range of -40°C to +85°C.
