OPA615: OPA615 DC restoration and video amplification

Muhammad Moosa

Part Number: OPA615

Hi ! I am currently working with a PAL based composite video. The video has 0.5-1V peak to peak amplitude and 15 MHZ bandwidth. I want DC restoration and a gain of +2V/V. How can it be done with OPA615 ?

Hi,

You can reference figures 40 and 41 in the OPA615 datasheet that show two examples of DC restoration circuits. The example from figure 40 has a gain equal to R2/R1, which you can set to 2 V/V.
