MAX4259数据手册ADI中文资料规格书

描述 Description

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 combination of ultra-high speed and low power makes them suitable for use in general-purpose high-speed applications, such as medical imaging, industrial instrumentation, and communications systems.
The MAX4159/MAX4259 have address latching and high-impedance output disabling, allowing them to be incorporated into large switching arrays. They are available in 14-pin SO and 16-pin QSOP packages. The MAX4158/MAX4258 have no address latching or output disabling, but are available in space-saving 8-pin µMAX® and SO packages.
