350MHz/250MHz, 2-Channel Video Multiplexer-Amplifiers
_______________General Description ____________________________Features
The MAX4158/MAX4159/MAX4258/MAX4259 are wideband, 2-channel, noninverting video amplifiers with input multiplexing, capable of driving ±2.5V signals into 50Ω or 75Ω loads. These devices are current-mode feedback amplifiers; gain is set by external feedback resistors. The MAX4158/MAX4159 are optimized for unity gain (0dB) with a -3dB bandwidth of 350MHz. The MAX4258/ MAX4259 are optimized for gains of two (6dB) or more with a 250MHz -3dB bandwidth. These devices have low (0.01%/0.01°) differential gain and phase errors, and operate from ±5V supplies.
These devices are ideal for use in broadcast and graphics video systems because of their low, 2pF input capacitance, channel-to-channel switching time of only 20ns, and wide, 130MHz 0.1dB bandwidth. In addition, the co...
