• AD5512A DGND and AGND are internally connected?

    Hello,

    the question is simple, Analog and Digital ground of the chip AD5512A are connected togheter ?

    And the Exposed PAD, where is connected ? 

    I have a system with two isolated ground and I have to keep them absolutely isolated.

    Thanks in advance.

  • how to interface AD5542A dac ic with FPGA memory to provide input data to Din pin of AD5542A?

    Around 256K data is stored as a bunch in memory and we need to convert this digital data to analog at once by applying it to AD5542A dac ic. As chip select need to go low to high after each 16 bit data to latch it to dac. 

  • 你好,有个AD8628的问题想问一下

    你好,我看AD8628的文档说AD8628是单电源供电,但是在AD5512A的文档里,说AD5512A的双极性输出操作是,给出的例子里用的就是AD8628,但是图里面是接的确实双电源,如下图

    我使用的AD5512A的双极性输出,那应该是5v单电源,还是双电源+-5V?谢谢

  • Reference of AD5542A in bipolar mode

    Dear AD engineers,

    Could I ask if +5V/-5V is supported for AD5542A in bipolar mode? It is specified in datasheet everywhere that a 2.5V reference should be used, such as in page 8: Pin REF Connect this pin to an external 2.5 V reference.

    Thanks a lot…

  • RE: DAC选型失败,求推荐一个DAC能产生一个50KHZ的正弦波

    您好。DAC更新速度会受到建立时间,和通讯速度,以及其他一些时序要求的影响。

    对于您的应用可以参考使用DDS产生正弦信号,可以参考AD9837。希望使用DAC的话,可以参考AD5512A,AD5552

    I or V out可以参考AD5450,是电流输出的DAC,在Voltage-Switching Mode连接时可以做电压输出

    unbuffered vout和voltage out输出阻抗不同

    AD5398, 120mA Current sinking DAC With Reduced Current Range

    I'm working with the AD5398. I don't need the full 120mA range of the device.  Is it possible to get the full 10bit resolution over a smaller current range, say 20mA?   What would be the…
