• RE: AD7091R-5 I2C

    Hiroyuki,

    So I spoke to the designer and I believe the model you provided in your thread above is accurate for SDA in that there are protection diodes in the SDA pad for when the device is to be a SPI part.   The problem is that POWER must be applied for…

  • AD7091R-5 command mode

    I read datasheet  Rev. 0 | Page 31 of 34.

    >6. The master sends the first data byte (0x03) to the configuration register, which selects the command mode.

    But I think 0x03 doesn't mean a command mode.

    AUTO and SRST are set by 0x03.

    Shouldn't I…

  • AD7091R-5 Conversion problems

    I was disappointed to find that there's no Linux driver available for the AD7091R-5 part our hardware team have selected. I'm trying to adapt a driver for a similar part, but I'm having trouble getting a sensible conversion value out of the device.…

  • AD7091R-5 and AD7415 SDA, SCL

    Hi

    I'm DFAE in Japan. Our customer connect AD7091R-5, AD7415 and others with I2C interface in the system. When the system is powered off, both SCL and SDA are into LOW. His end-user suspects that there is an IC in his circuit that pulls those signals…

    Tim,

    Unfortunately, we don't have it. At this moment, we are supporting AD7091R and AD7091R-5 (4 channels but I2C) - Linux Drivers [Analog Devices Wiki].

  • AD7091R-5 using internal reference

    Hello,

    until now I'm not able to use the AD7091R-5 with internal reference of 2,5V.
    I'm sending this bytes to the AD7091-R to configure it :
    \x02\x06\xC1\x01\x0F\x00
    meaning config reg 0x02 is set to 0x06C1
    -> CMD Mode = 1,
    -> Software Reset…

  • Cheap way to reset AD7091R-5

    I am starting a small aquisition Circuit with the AD7091R-5. I only have IIC w/o Reset line. I wondered if the Reset can be connected to a R and C in series:

    Or should I use a reset circuit for this application?

    Best Regards,
