A good video amplifier has a
bandwidth considerably greater
than that ofthe average video
signal. Furthermore, it is utterly
stable, and provides input and
output impedances that match
directly to coax cable. Phew!
What requirements! Weil, this
article describes such an
amplifier, based on Maxim's
MAX457, which contains two
very fast CMOS opamps.
Applications: an ultra-compact
video splitter/crosspoint
amplifier, or a flash D-A
converter driver.
