描述

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 multiplexing 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 distribution amplifier, see the MAX4137/MAX4138 data sheet.
