• AD7091R-8 problem

    hi every one,

    I have problem to run AD7091R-8, I use fpga to use this ADC but when I initialize the ADC and set the registers and then I want to read back the registers to verify them. but there is no signal in SDO pin, I think maybe the IC didn't receive…

  • Faulty values being read on AD7091R-8

    Hi,

    We are using AD7091R-8 to read 3 signals on 3 channels. We are able to enable channel sequencer and read back the correct channel ID values.

    However, the conversion value is not correct. If only one channel is enabled and val;ues are read, the data…

  • AD7091r-8无法采集数据

    对AD7091r-8进行寄存器写，并读回都正确，唯独进行数据采集是没有输出，发出采集命令0x00XX后，sdo返回为0；对CHANNEL SEQUENCER进行写操作后，也没有输出，读CHANNEL SEQUENCER为写入数据。实在不解？

  • AD7091R-8 : settling time

    Hello,

    I have some questions about AD7091R-8.

    The AD7091R-8 has a MUXout pin.

    Q1:

    How long settling time is necessary for output of Muxout pin after the channel register is written?

    Q2:

    It is a question about the MUXout when the same channel is…

  • AD7091R-8 Question

    Hi

     

    I have a question AD7091R-8.

     

    【Question 1】
    What happens to the conversion result if I repeat the above sequence during sequencer operation?
    At this time, reset is not performed.

    [Situation that is occurring]
    Search result data is acquired with…

    Hello

    Please let me know  below  about read/write of AD7091R-8

    1:  I would like to read  conversion result of particular channel only  without use of sequencer.
    Should I use the method  described in datasheet P.35  Figure 54. Channel Sequencer Multiple Channel…

  • AD7091R-8 Channel Register

    Hi

    I have a question AD7091R-8.

    This is how to set the channel register.
    Which of the following two is correct? Or are they different?

    ① First set the Address (including R / W). The lower 10 bits are set to '0' → Next Channel Register is set. For example…

  • AD7091R-8 Start up

    Hello All

    Please let me know your advice about start up sequence of AD7091R-8.

    I think that I set register setting  as attached file after power up.

    (write needed all register setting after default setting by reset pulse)

    Is my understanding correct…
