• AD5722输出问题

    利用三片AD5722芯片来构成一个菊花链结构,MCU是dsp28377,数据更新的方式是在数据传输过程中,LDAC信号保持高电平,在使能信号拉高之后才变成LDAC才变成低电平。发现只有第一块芯片的两个DAC通道有输出,其他四个通道没有输出,并且第一块芯片的输出一路输出2.7V,一路输出-7.2V,与预期不一样。更改DAC寄存器的数据值也不起作用,仍然为这两个值。应该如何解决呢?

  • AD5722 Output Range

    Hi

    My customers are planning to use the AD5722 with REFIN = 3 V.
    Please give me your wisdom about this plan.

    They expect 12V output with Output Range = + 10.8V setting.
    Since Internal Gain Values is 4.32, it seems there is no problem with the plan.
    However…
  • AD5722 - EXPOSED PAD + NC Pins

    Hello there,

    I am working on a design that involves an AD5722, operating from dual supplies (± 15 V) and bipolar output (output range ± 10 V).

    I have two "simple/dummy" questions:

  • RE: AD5752 not working

    Hi,

    You may refer to the "CONFIGURING THE AD5722/AD5732/AD5752" section of the datasheet.

    Correct power sequence should be followed, then set the output range then power up the channel through the power control register.

    If it still doesn…

    My initial write on the AD5754 is ignored ?

  • AD5752 Power Up Time

    In the AD5752 datasheet a power up time of 10uS is required before writing to the DAC - what happens if I write to the DAC before this?

  • AD5722R SDO Question

    If SYNC pin is high Is the SDO pin of the AD5722R tri stated ?

    Can several AD5722R devices share one common SDO line on the data bus and just be selected by the SYNC input?

    Or will each of them need its own SDO line or be daisy chained?
