1-Input/4-Output Video Distribution Amplifiers

Datasheet
The MAX4137/MAX4138 are 1-input/4-output voltage-
feedback amplifiers that combine high speed with fast
switching for video distribution applications. The
MAX4137 is internally set for a closed-loop gain of
2V/V, while the MAX4138 can be externally set for gains
of 2V/V or greater.
The MAX4137 achieves a -3dB bandwidth of 185MHz,
with 0.1dB gain flatness to 40MHz. The MAX4138’s
-3dB bandwidth is 140MHz, with 0.1dB gain flatness to
40MHz. 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 MAX4137/MAX4138’s on-board
logic selects any combination of the four signal outputs.
Each output is capable of swinging ±2V and delivering
up to 65mA of current.
For applications that require a 1-input/6-output distribu-
tion amplifier, see the MAX4135/MAX4136 data sheet.
