• AD7091R-5 GPO1、2 Attributes

    AD7091R-5 GPO0 can be set by register as Open-Drain or CMOS, but GPO1 and GPO2 are not explained.

    Which one is GPO1 and GPO2? (Open-drain or CMOS)

  • AD7091R-5

    The page 8 of AD7091R-5 datasheet describes VDrive as "The voltage range on this pin is 1.8 V to 5.25 V and may differ from the voltage range at VDD, but must never exceed it by more than 0.3 V", however AD7091R does not have this limitation.…

  • AD7091R-5 I2C


    I'm a DFAE in Japan. Our customer give us a question. There is a MOSFET inside SDA pin of AD7091R-5. On the other hand, is there NO MOSFET inside SCL pin of AD7091R-5? According to Table 5, we couldn't see Open-drain output about SCL as follows.…

  • AD7091R-5 driver


    I can't see a download link for your AD7091R-5 driver for Linux anywhere. I looked here: AD7091R5 ADC Linux Driver [Analog Devices Wiki] 

    Can someone please provide a link?

  • AD7091R-5 I2C Address Control

    Dear All:

    AD7091R-5 table 8. Slave Addresses show AS0 & AS1 pin same time It's can NC ,If ESD conductive test or a lot of noise around the motor ,will it be disturbed by noise or act abnormally? have any suggest to me refer. thnaks



  • 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 using internal reference


    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 :
    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,


  • AD7091R-5 and AD7415 SDA, SCL


    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…
