Ultralow Power SD Video Filter with Load Detection

FEATURES Third-order, low-pass video filter 1 dB flatness out to 6 MHz 27 dB rejection at 27 MHz Low quiescent current: 4.7 mA typical Low power-down current: 24 μA typical Load detection capability SAG correction Allows use of smaller capacitors in ac-coupled outputs Low supply voltage:

超低功耗标准清晰度（SD）视频滤波器 ，具有负载检测特性

ADA4431-1是一款完全集成的视频重建滤波器，它将卓越的视频指标与低功耗以及超低待机功耗进行完美结合，使之成为便携式视频滤波应用的理想选择。ADA4431-1能够检测视频负载是否出现在输出端，当负载没有连接时即处于关断状态。                     \n\n ADA4431-1采用低至2.5 V的单电源供电，同时提供要求最严苛的视频系统所需的动态范围。片上电荷泵提供虚拟负电源，可以将视频信号直流耦合，并将黑色电平设置为地电压，而同步信号则以地电压以下300 mV的电压干净地通过。\n\n 电荷泵关闭时，ADA4431-1提供直流偏置，使同步端保持在地电压 • 三阶、低通视频滤波器\n1 dB平坦度带宽：6 MHz \n27 MHz抑制：27 dB \n\n• 低静态电流： \n4.7 mA（典型值） \n\n• 低掉电电流： \n24 μA（典型值） \n\n• 负载检测功能 \n\n• SAG校正 \n允许在交流耦合输出中使用较小电容 \n\n• 低电源电压： 2.5 V至3.6 V;
