5 、 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
