• AD4111 Incorrect Readings


    We are using the EVAL-AD4111SDZ, using single ended for CH0, so when we apply the input voltage and hold it, we read the data register and that data keeps changing (not stable) even the Vin is the same, when we start form 0Vin and we keep reading…

  • AD4111 input range


    I am using AD4111 in my circuit for reading RTD. My input range is very low and it is around several millivolts. I do not need the wide range of AD4111. Is there any way to limit the rage so as to achieve higher precision?  Right now my precision is…

  • ADC data read from AD4111

    Hi all,

    I am facing the issue regarding ADC data read from the AD4111 device

    Hardware setup:

    1. EVAL-AD4111/12SDZ Board
    2. PIC microcontroller
    3. The temperature sensor (4-20mA output) is connected to IIN0 and GND terminals of  EVAL-AD4111/12SDZ Board


  • AD4111 open wire detection

    We are going to use AD4111 in our project.

    We want 4 single-ended bipolar ±10 V voltage inputs, the input pins are VIN0~VIN3.

    Open wire detection function is necessary.

    Here are my questions

    1. In datasheet, It says The VIN0 and VINCOM…

  • About the output data rate of AD4111


    I have a question about the output data rate of the AD4111.

    I use several types of ODR (Output Data Rate), but it works normally when it is 59.52, but when I operate it in continuous conversion mode at 49.68, DOUT / RDYn does not become L and the…

  • Channel switching in continuous conversion mode of AD4111

    I have a question about channel switching in continuous conversion mode of AD4111.

    Is it possible to disable CH0 and enable CH1 to switch channels while performing continuous conversion with CH0 enabled?

    Is it possible to switch channels only at…

  • AD4111 Aperture Time and Uncertainty

    Hi Folks,

    I would like to know what the aperture time and associated uncertainty is for the AD4111.  Can you help me understand it.  It seems to be missing from the ADC specifications.

    Thank you.

  • AD4111 crosstalk

    To whom it may concern,

    We are facing some crosstalk issues with the AD4111 in differential voltage mode. Applying 20Vpp at one channel results in 0.6Vpp at the other three channels (3% or -30dB). The crosstalk is not only seen when the input is left…

  • i am getting incorrect values when reading ad4111 channel records

    before addressing the problem, I would like to point out the tools I use.

    equipment used:

    Adc board: EVALAD4111/12SDZ


    development board :Easymx PRO v7 (STM32F107)



    the compilation method: non os

    apis used for compilation: Analog…



    I have a question about GPIO CONFIGURATION REGISTER (0x06) for AD4111.

    In the explanation of ERR_DAT on P52, there is a description about the input and the operation as a GPO, but there is no description in the open drain error mode.

    If the bit…
