The MAX440 combine a unity-gain stable, wideband video amplifier with a high-speed, 8 channel multiplexer (mux). The mux"s fast 15ns switching time and the amplifier"s low differential gain and phase errors (0.04% and 0.03, respectively) make the MAX440 ideal for broadcast quality video applications. Both devices operate from ±5V power supplies and typically consume only 350mW. The on-board video amplifier features a 160MHz unity-gain bandwidth, 250V/µs slew rate, and directly drives a 1500 load to ±3V. Pin-selectable frequency compensation allows the amplifier"s AC response to be optimized without external compensation components or complex calculations. Slew rates of 370V/gs are obtainable for applications with a closed-loop gain of 6dB or greater. An enable control on the MAX440 places the amplifier output into a high-impedance state, allowing multiple devices to be paralleled to form larger switch matrices. The mux"s low channel-input capacitance (4pF with channel on or off) maximizes high-speed performance. No input channels are located on adjacent package pins, minimizing crosstalk and simplifying board layout.
