6500V/µs、宽带、高输出电流、单端至差分线驱动器，带有使能端

MAX4447/MAX4448/MAX4449单端至差分线路驱动器专为高速通信而设计。这些器件利用电流反馈来获得更大的带宽，可提供高达405MHz的全功率带宽，并具有高达6500V/µs的压摆率。MAX4447具有+2V/V的固定增益和430MHz的小信号带宽。MAX4448/MAX4449的小信号带宽分别为330MHz和400MHz，并分别针对+2V/V和+5V/V的最小增益配置进行了内部补偿。为了获得更大的设计灵活性，MAX4448/MAX4449支持使用外部增益设置电阻进行可变增益选择。低功耗使能模式可将电流消耗降至5.5mA以下，并将输出置于高阻抗状态。\n\n MAX444 • 6500V/µs压摆率(MAX4449)\n\n• 小信号带宽\n• 430MHz (MAX4447)\n\n• 330MHz (MAX4448)\n\n• 400MHz (MAX4449)\n\n\n\n\n• 0.1dB增益平坦度：200MHz (MAX4447)\n\n• 130mA输出驱动电流\n\n• +2V/V内部固定增益(MAX4447)\n\n• 外部增益选择\n• >+2V/V (MAX4448)\n\n• >+5V/V (MAX4449)\n\n\n\n\n• 100kHz时的SFDR为-78dB\n\n• 低差分增益/相位：0.01%/0.02°\n\n• 超;
