• AD7091R-8

    Hello
    I'm trying to set up communication with AD7091R-8. In setup I send following SPI command: 0X0CFF, 0X08FF, 0XFFFF, 0XFFFF, 0X00FF. Then I periodically send 0X0020 and I'm trying to read channel 5. I'd like to read one channeland them sequential readings…

    Hi, Terumasa.

    The on resistance of the multiplexer with a 5 V supply is typically 50 ohms, while with a 2.5 volt supply the on resistance typically increases to 100 ohms.  This is outside of the resistance mentioned on page 19 of the datasheet. By the…

  • 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…

  • 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 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…

  • RE: AD7091R-8  READING CONVERSION RESULT

    Thanks for the captures.

    Now, I think AD7091R-8 does not start conversion with the /CONVST pusles. The cause may be AD7091R-8 doesn't recognize the /CONVST or AD7091R-8 gets latch-up in some state.

    I saw the power supplies VDD=5V takes about 50ms…

    EHILLEL820,

    You absolutely can read from channel 0 to channel 3 (1-4) in sequential order.   Assuming you are using the AD7091R-4, you can simply program the channel register (ADDR = 0x01) with code 0x000F to enable channels 0 to 3 for conversion.  

    If you…
