• RE: AD7091R-5

    Yes. The voltage range on the VDRIVE pin on AD7091R-5 is from 1.8V to 5.25V. However, the voltage on the VDRIVE pin must never exceed the voltage on the VDD pin by more than 0.3V for ADR7091R-5.

    For the AD7091R, the voltage on the VDRIVE pin can be anywhere…

  • 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?



  • Device Reset for AD7091R-5


    Could you please recommend ADI's IC as the device reset for AD7091R-5 ?



  • 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.…

  • 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,


  • RE: AD7091R-5 using internal reference

    Hi Wollli,

    Apologize, I was referring on the wrong device (AD7091R). From the Table 3 of the AD7091R-5, Analog input voltage should be from -0.3V to Vref + 0.3 V only with respect to ground. Having input voltage greater than the maximum voltage will…

  • 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…

  • AD7091R-5 RESET Pin Power Up Timing


    I read datasheet of AD7091R-5. (Rev. 0)

    I felt a doubt about timing of a RESET pin.

    Shouldn't it be corrected as figure 35 was drawn by a red line?

    Give my best regards.
