_______________General Description

The MAX4158/MAX4159/MAX4258/MAX4259 are wide­band, 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 oper­ate from ±5V supplies.

These devices are ideal for use in broadcast and graphics
video systems because of their low, 2pF input capaci­tance, channel-to-channel switching time of only 20ns,
and wide, 130MHz 0.1dB bandwidth. In addition, the com­bination of ultra-high speed and low power makes them
suitable for use in general-purpose high-speed applica­tions, such as medical imaging, industrial instrumentation,
and communications systems.

The MAX4159/MAX4259 have address latching and high­impedance output disabling, allowing them to be incorpo­rated 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.

Stresses beyond those listed under “Absolute Maximum Ratings” may cause permanent damage to the device. These are stress ratings only, and functional
operation of the device at these or any other conditions beyond those indicated in the operational sections of the specifications is not implied. Exposure to
absolute maximum rating conditions for extended periods may affect device reliability.

Note 2: Does not include external feedback network resistance.
Note 3: Applies to all digital input pins (EN, LE, and A0).
Note 4: Specified with feedback network chosen for optimal AC performance. See Tables 1 and 2 for recommended component

values.

Note 5: Input test signal: 3.58MHz sine wave of amplitude 40IRE superimposed on a linear ramp (0IRE to 100IRE). IRE is a unit of

video-signal amplitude developed by the International Radio Engineers. 140IRE = 1.0V.

Note 6: See timing diagram (Figure 5).
Note 7: Channel-switching time specified for switching between the two input channels; does not include signal rise/fall times for

switching between channels with different input voltages.

Note 8: Guaranteed by design; not production tested.
Note 9: Output enable/disable delay times do not include amplifier output slewing times.
Note 10: Switching transient measured while switching between two grounded channels.
