Integrated Triple Video Filter and Buffer with Selectable Cutoff Frequencies and Multiplexed Inputs for RGB, HD and SD
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.
