The MAX4158/MAX4159/MAX4258/MAX4259 are wide-
band, 2-channel, noninverting video amplifiers with input
multiplexing, capable of driving ±2.5V signals into 50Ω or
75Ω loads. These devices are current-mode feedback
amplifiers; gain is set by external feedback resistors. The
MAX4158/MAX4159 are optimized for unity gain (0dB)
with a -3dB bandwidth of 350MHz. The MAX4258/
MAX4259 are optimized for gains of two (6dB) or more
with a 250MHz -3dB bandwidth. These devices have low
(0.01%/0.01°) differential gain and phase errors, and oper-
ate from ±5V supplies.
These devices are ideal for use in broadcast and graphics
video systems because of their low, 2pF input capaci-
tance, channel-to-channel switching time of only 20ns,
and wide, 130MHz 0.1dB bandwidth. In addition, the com-
bination of ultra-high speed and low power makes them
suitable for use in general-purpose high-speed applica-
tions, such as medical imaging, industrial instrumentation,
and communications systems.
The MAX4159/MAX4259 have address latching and high-
impedance output disabling, allowing them to be incorpo-
rated into large switching arrays. They are available in
14-pin SO and 16-pin QSOP packages. The MAX4158/
MAX4258 have no address latching or output disabling,
but are available in space-saving 8-pin µMAX and SO
packages.
