Analog Multiplexer/Amp Single 8:1 20-Pin PDIP N

The MAX455 combine the 50MHz video amplifier, of the MAX452, with an on-board multiplexer offering 2, 4, or 8 channels respectively. Optimized for video applications, these amplifiers will directly drive al50 ohm load to ±2V, and will swing ±1V into a 75 ohm load. All amplifiers are unity-gain stable and do not require external frequency compensation components. The MAX455 operate as positive-gain amplifiers, gain being set by two external resistors. Since they are connected as non-inverting amplifiers, their minimum closed-loop gain is 0dB. In most applications the amplifier"s closed-loop gain will be set at OdB or + 6dB (1 V/V or 2 V/V), which guarantees a minimum bandwidth of 25MHz.
