• Inquiry of AD7091R-2 SPI SDI

    Dir Sir,

    Would you help to clarify the SPI timing diagram Fig.4 below in datasheet ? It seems the SDI acquired on rising edge that is conflicted with description of  pin function Table 5 on page 8. Thanks.

  • AD7091R-2,-4 External Ref Input Range

    HI,,

     

    I have a question , AD7091R-2,-4 External Reference Input range.

    There is 1.0 - Vdd V in Page 3 , at dataseat

    But , there is 2.5 - Vdd in Page 18 , at dataseat.

     

    I think external reference input range is 1.0 - Vdd .

    Which is correct?

    1. i want to read from channel 1 to 4 how can i  do it

    2.i want to do in sequence how can i  do it

  • I want to run in sequence mode ad7091r-2, how do I do that?

    Using the AD7091r-2 and I want to have it sequence between chan 0 and 1 all the time.

    How do I configurate that to happen?

  • AD7091R使用咨询

    使用AD8275和AD7091R-4BCPZ-RL7设计4路ADC采集电路上报给CPLD

    1.在测量0~10V输入时,AD8275的ref1和ref2接GND,AD7091R的ref接2.048V

    2.在测量-12V~+12V输入时,AD8275的ref1和ref2接2.5V,AD7091R的ref接5V(ref191更换为ref195)

    问题:

    1.使用1片ref192是否可以满足4片AD8275的参考电压的电流需求?

    2.AD7091R的muxout直连ADCin在PCB布线上是否有屏蔽要求…

    Hi,

    By using external reference would it increase measurement accuracy ?

    If so, which reference IC is recommended ?

  • RE: AD7091R Evaluation Software

    Hi Rekha,

    Can you confirm if there is any power getting to the AD7091R-2 board? There are two LEDs in the "Power Management" section called "PWR-IN" and "PWR-GOOD" that don't appear to be lit up.

    Regards,
