I am using AD8072JRZ Current Feedback Amplifier to Buffer the Video Output, In Datasheet they Mention Only for Gain 2 Amplification. But I have a Doubt is this part will amplify for gain 1 Because I want to do Gain Adjustment.
Each amplifier’s inputs and output are accessible providing added gain setting flexibility. The closed-loop frequency response of a current feedback amplifier is a function of the feedback resistor. A smaller feedback resistor will produce a wider bandwidth response. However, if the feed-back resistance becomes too small, the gain flatness can be affected. for more detail refer Bandwidth vs. Feedback Resistor Value section in datasheet

If the monitor is expecting video from a 75 Ohm source, including any cable runs. Normally the source will have an output buffer with 2x gain and a 75 Ohm series resistor driving into a 75 Ohm cable. Refer : https://ez.analog.com/video/f/q-a/121617/video-driver-buffer/362786#362786
