    Timing about AD7847:

    In the AD7847 datasheet, I got the truth table and write timing diagram as below:

      

    I have confusions:

    (1) from the truth table, I think that both CS and WR rising edge can latch data into the DAC.

    (2) But from the timing diagram…

  • AD7837/AD7847 DAC interface

    Dear All,

    Can i make interface with DAC ( AD7837) using Microprocessor have I/O ports with logic voltage levels equal to 3.3 volt??

    and if not there is DAC with logic level I/O equal to 3.3 volt??

    Thanks in Advances,

  • long term drift over time

    I need Long Term Stability parameter for the following DAC's :
    AD5544
    AD7847
    AD7846

     

    The long term drift over time is included in the max and min specifications of
    the part. For example, we guarantee that the full-scale gain…
  • AD7847,0代码附近出现20mv的失真

    1.电源电压正负12V

    2.输入为有效值位7V的AC.

    3.设置为1111 1111 1111 时 输出正常,误差4个MV左右

    4.设置为0000 0000 0000 时 输出正常,误差4个MV左右

    5.设置1000 000 000时,理论输出0V,实际输出20mv左右(四个通道出现相同情况)

    5.设置1000 000 0001、1000 0000 0010、1000 000 0011,1000 000 0100时,实际输出20mv左右(四个通道出现相同情况),出现0v输出周围失真…
