产品特色

1. AD9649采用1.8 V单模拟电源供电，而数字输出驱动器采用

独立的电源供电，以适应1.8

V至3.3 V系列的逻辑电平。

取得专利的采样保持电路在最高200

MHz的输入频率下仍

保持出色的性½，而且成本½、功耗½、易于½用。

标准串行端口接口(SPI)支持各种产品特性和功½，例

如：数据输出格式化、内部时钟分频器、省电模式、

DCO和数据输出(D13至D0)时序和偏移调整、以及基准

电压源模式等。

4. AD9649采用32引脚LFCSP封装，符合RoHS标准，与12

½ADC

AD9629和10½ADC AD9609引脚兼容，因此采

样速率为20

MSPS至80 MSPS的10½和14½½换器可½松

实现升级。

应用

通信

分集无线电系统

多模式数字接收器

GSM、EDGE、W-CDMA、LTE、CDMA2000、WiMAX、

TD-SCDMA

智½天线系统

电池供电仪表

手持式示波器

便携式医疗成像

超声

雷达/LIDAR
