Description
The FHP3194 is a 4:1 analog multiplexer designed for high-speed video applications. The output amplifer is a high-speed current feedback amplifer that offers stellar large signal performance of 500MHz -3dB bandwidth and 90MHz 0.1dB bandwidth. The gain of the output amplifer is selectable through two external resistors (Rf and Rg), allowing further design flexibility. The 2Vpp bandwidth performance and 2200V/µs slew rate exceed the requirements of high-defnition television (HDTV) and other multimedia applications. The output amplifer also provides ample output current to drive multiple video loads.
