_______________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.
