Operational amplifier for analog video

Elhanan Shifman

Hey

I'm looking for two operational (regular and FDA) amplifiers for analog RCA Composite video signal that will allow me to convert between deferential video input to Single Ended video input and vice versa, and also to add resistor close loop gain level.

Thank you

    At one time, there were product portfolio's in the industry that did exactly this - analog video to differential and back. TI never did any of these to my knowledge, but there are various applications techniques using op amps and FDA's of course. would need considerably more signal requirement info to pursue either path. Speed, swings cable length etc (for twisted pair, there are also equalizing receivers out there if need be).

    Hello Elhanan,

       Thank you for sharing the type of application. Are you looking for a special function video amplifier such as these products. Or any single-ended or differential ended amplifier would do? As Michael mentioned, would you be able to share some of the critical specifications such as BW, power supplies, output/input voltages, and load characteristics?

      Also here is a app note on a low cost video driver application as a reference. 

    Thank you,

    Sima
