4通道、LVDS、双路输出、激光二极管驱动器，内置振荡器

AD9668是一款用于高性能CD-RW和DVD可刻录驱动的激光二极管驱动器。它包含4个通道，分别针对4个不同的光功率水平；读取通道产生连续输出功率水平，而通道1、通道2和通道3可用作写入通道，由LVDS或TTL接口控制。OSCEN引脚也受LVDS或TTL信号控制。所有通道在选定的LD输出引脚处求和，其中写入通道1可贡献至少275 mA输出电流，写入通道2和写入通道3分别可贡献至少170 mA和150 mA输出电流。输出电流水平由外部电阻设定，该电阻在WxSET引脚处将输入电压转换成电流。\n\n该器件内置一个片内振荡器，提供输出电流调制功能并能减少激光模式跳变。四个外部电阻允许针对每个输出设置 • 双通道、电流控制输出电流源，带4个输入通道\n\n• TTL可选输出\n\n• 稳定的片内振荡器，带独立的频率和幅度控制\n\n• TTL或LVDS可选写入通道使能与可选振荡器使能\n\n• 读取通道的最小输出电流：150 mA\n\n• 写入通道1的最小输出电流：275 mA\n\n\n\n• 写入通道2的最小输出电流：170 mA\n\n• 写入通道3的最小输出电流：150 mA\n\n• 上升时间/下降时间： 0.8 ns\n\n• 低输出过冲\n\n• 低功耗\n\n• 5 V单电源供电（±10%）;

Ultrafast Comparators

GENERAL DESCRIPTION The AD96685 and AD96687 are ultrafast voltage comparators. The AD96685 is a single comparator with 2.5 ns propagation delay; the AD96687 is an equally fast dual comparator. Both devices feature 50 ps propagation delay dispersion which is a particularly important characteristic
