1-Input/6-Output
Video Distribution Amplifiers
_______________General Description
The MAX4135/MAX4136 are 1-input/6-output voltage-
feedback amplifiers that combine high speed with fast
switching for video distribution applications. The
MAX4135 is internally set for a closed-loop gain of
2V/V, while the MAX4136 can be externally set for gains
of 2V/V or greater.
The MAX4135 achieves a -3dB bandwidth of 185MHz,
with 0.1dB gain flatness to 40MHz. The MAX4136’s
-3dB bandwidth is 140MHz. Both devices deliver a
1000V/µs slew rate, as well as exceptional full-power
bandwidths of 185MHz and 140MHz, respectively.
A 25ns channel switching time enables rapid multiplex-
ing for picture-in-picture applications, yet maintains a
high off-isolation of 75dB and all-hostile crosstalk of
-50dB (f = 30MHz). The MAX4135/MAX4136’s on-board
logic selects any combination of the six signal outputs.
Each output is capable of swinging ±2V and delivering
65mA.
For applications that require a 1-input/4-output distribu-
tion amplifier, see the MAX4137/MAX4138 data sheet.

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.
