_______________General Description
The MAX4135/MAX4136 are 1-input/6-output voltagefeedback amplifiers that bine 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 -3d B bandwidth of 185MHz, with 0.1d B gain flatness to 40MHz. The MAX4136’s -3d B 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 75d B and all-hostile crosstalk of -50d B (f = 30MHz). The MAX4135/MAX4136’s on-board logic selects any bination of the six signal outputs. Each output is capable of swinging ±2V and delivering 65m A. For applications that require a 1-input/4-output distribution amplifier, see the MAX4137/MAX4138 data sheet.
