MAX442
Description
The MAX442 bines a 140MHz video amplifier with a high-speed, 2-channel multiplexer in an 8-pin package. With its 36ns switching time and low differential gain (0.07%) and phase (0.09°) errors, it is ideal for broadcast-quality video applications. The device is designed to drive both 50Ω and 75Ω cables, and can directly drive a 75Ω load to ±3V. The MAX442 video amplifier is pensated for unitygain stability, and features a 140MHz bandwidth and a 250V/µs slew rate. The multiplexer’s low input capacitance (4p F with the channel on or off) maximizes highspeed performance, and a ground pin separating the two input channels minimizes crosstalk and simplifies board layout. The MAX442 operates from ±5V supplies and typically consumes 300m W. For applications that require more input channels, see the data sheets for the MAX440 8channel mux/amp and the MAX441 4-channel mux/amp.
