• About AD7927 2×REF MODE

    When the range of 0V to 2 × REFIN is selected (RANGE bit = 0),
    How much variation (FS value is) is the 2.5V input from the outside?

    Or because the gain error is the same, the input side is attenuated,
    Is the FS value the same?

  • AD7927: Vdrive voltage

    In page 3 of the datasheet, the specification indicates that the analog input
    can be 0~2*REFin. The condition is AVDD/VDRIVE=4.75~5.25V. It requires both
    AVDD and VDRIVE to be 5V. However, in the datasheet, it says the Vdrive can be
    3V to interface…

  • Read all channels from AD7927

    Hi friends.

    I try AD7927 and read from 1 channel is OK.

    But ho to read all channel without stop communication?

    How to set SEQ and SHADOW? And what I must send to device?

    For example:

    Register value is: 0xC3B

    I send this value to device.

    Send…
