AD9834 20 mW功耗、2.3 V至5.5 V、75 MHz完整DDS

AD9834是一款75 MHz、低功耗DDS器件,能够产生高性能正弦波和三角波输出。其片内还集成一个比较器,支持产生方波以用于时钟发生。当供电电压为3 V时,其功耗仅为20 mW,非常适合对功耗敏感的应用。

AD9834提供相位调制和频率调制功能。频率寄存器为28位;时钟速率为75 MHz,可以实现0.28 Hz的分辨率。同样,时钟速率为1 MHz时,AD9834可以实现0.004 Hz的分辨率。影响频率和相位调制的方法是通过串行接口加载寄存器,然后通过软件或FSELECT/PSELECT引脚切换寄存器。

AD9834通过一个三线式串行接口写入数据。该串行接口能够以最高40 MHz的时钟速率工作,并且与DSP和微控制器标准兼容。

该器件采用2.3 V至5.5 V电源供电。模拟和数字部分彼此独立,可以采用不同的电源供电;例如,AVDD可以是5 V,而DVDD可以是3 V。

AD9834具有掉电引脚(SLEEP),支持从外部控制掉电模式。器件中不用的部分可以掉电,以将功耗降至最低。例如,在产生时钟输出时,可以关断DAC。

该器件采用20引脚TSSOP封装。

应用 - 频率刺激/波形产生 - 频率相位调谐和调制 - 低功耗RF/通信系统 - 液体和气流测量 - 传感器应用:接近度、运动和缺陷检测 - 测试与医疗设备
