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.
