Description

The FHP3194 is a 4:1 analog multiplexer designed for

high-speed video applications. The output amplifier is a

high-speed current feedback amplifier that offers stellar

large signal performance of 500MHz -3dB bandwidth and

90MHz 0.1dB bandwidth. The gain of the output amplifier

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-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 inputs. The FHP3194 offers better than 70dB channel

isolation.

The FHP3194 offers both shutdown and disable capability.

During shutdown, the FHP3194 consumes only 2.5mA

of supply current. During disable mode, only the output

amplifier is disabled, reducing output glitches and allowing

for multiplexer expansion.
