ADA4411-3ARQZ-R7

ADA4411-3ARQZ-R7 is an integrated triple video filter and buffer with selectable cut-off frequencies and multiplexed inputs for RGB, HD/SD. It is a comprehensive filtering solution designed to give designers the flexibility to easily filter and drive various video signals, including high definition video. Cut-off frequencies of the sixth-order video filters range from 9MHz to 36MHz 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. It has a rail-to-rail output that can swing 4.5V p-p on a single 5V supply. Output voltage offset is continuously adjustable over an input-referred range of ±500mV by applying a differential voltage to an independent offset control input. It is used in applications such as set-top boxes, personal video recorders, DVD players and recorders, HDTVs, projectors.
