The output amplifier is a high-speed current feedback amplifier that offers stellar large signal performance of 335MHz -3dB bandwidth and 80MHz 0.1dB bandwidth. The gain of the output amplifier is selectable thru 2 external resistors (Rf and Rg), allowing further flexibility. The 2Vpp bandwidth performance, 1600V/µs slew rate, and 0.02% / 0.03° differential gain and phase exceed the requirements of high definition television (HDTV) and other multimedia applications. The output amplifier also provides ample output current to drive multiple video loads. Two address bits (A0 and A1) are used to select one of the four buffered inputs. The FHP3194 offers excellent 7.5ns switching times and better than 70dB channel isolation. The FHP3194 offers both shutdown and disable capability. During shutdown, the FHP3194 consu...
