Video Amplifier :ADA4759

ADA4859-3(triple) is a single-supply, high speed current feedback amplifier with an integrated

charge pump that eliminates the need for negative supplies in order to output negative voltages or

output a 0V level for video applications. The 195 MHz, large signal -3dB bandwidth at a fixed gain of 2,

as well as the 740 V/us slew rate, make this amplifier ideal for high resolution professional and

consumer video applications. The amplifier also has a wide input common-mode voltage range that

extends from 1.8V below ground to 1.2 V below the positive rail at 5V supply.
