Excellent Video Specifications:  
0.1dB Gain Flatness to 130MHz  
The MAX4158/MAX4159/MAX4258/MAX4259 are wide-  
band, 2-channel, noninverting video amplifiers with input  
multiplexing, capable of driving ±2.5V signals into 50or  
75loads. 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 -3d B b a nd wid th 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.  
0.01%/0.01° Differential Gain/Phase Error  
High Speed:  
350MHz -3dB Bandwidth (MAX4158/4159)  
250MHz -3dB Bandwidth (MAX4258/4259)  
700V/µs Slew Rate (MAX4158/4159)  
1000V/µs Slew Rate (MAX4258/4259)  
20ns Settling Time to 0.1%  
Fast Switching:  
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.  
20ns Channel-Switching Time  
<70mV Switching Transient  
Low Power: 100mW  
Directly Drive 75or 50Cables  
High Output Current Drive: >70mA  
Address Latch and High-Z Output Disable  
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.
