• EVAL-AD7190 window version

    Dear Sir / Madam,

    We would like to evaluate to EVAL-AD7190. However, we find that the software is not supported on Window 10. It is only up to Win7

  • AD7190 aincom引脚

    我现在在用ad7190测量两路差分信号,使用了ain1,2,3,4四个模拟输入端口。但是,我并没有将aincom端口悬空,而是将它在pcb上直接接地。我使能了ad7190的缓冲输入。手册上说在使能缓冲输入的情况下,模拟输入最小为AGND+250mv。在这种状态下,aincom引脚接地会损坏adc吗,虽然我没有使用它?如果不会损坏adc,那么会降低系统的性能吗?

  • basic qurestion about AD7190

    HI, I have several question about ad7190. In datasheet: A calibration
    should be performed when the gain is changed.

    I am comfused If i change gain to 2, then perform a calibrating and read out the calibration register, saving it in cpu, then i change to…

  • AD7190 daisy chain

    Hello.

    Is it possible to daisy chain the AD7190? 

    We have an application that requires about 10 ADC´s.

    Thanks for your help, 

    all the best,

  • AD7190

    We are having some product issues with the AD7190.

    If we don’t respond to the RDY# flag for a period of time then come back to reading the ADC we sometimes get a problem.

    To try and work out why it seems to deviate from the expected operation we read…

  • AD7190 problems

    Hi, I find two problem for using AD7190.

    1. When I use differential mode to measure a 1.5V AA battery, why i get 1.3V??  The pseudo differential is correct for 1.5V. 

    2. When there are input on Ain1 AIN2, the reading of temperature  sensor will be unstable…

  • AD7190

    Hi all,

     

    I am designing a precision industrial weight indicator by AD7190, what is the pros and cons of supplying digital part of the system with 3.3v versus 5v, power consumption is not important while reliability and noise have high priority.

     

  • AD7190: FAQs

    I need an help to configure an AD7190 to sample channel (+)AIN1 (-)AINCOM.
    I try to set the the configuration register to work with this channel, but when
    i read the conversion, the status register report a wrong value (0x05).
    This is the initialization…

  • AD7190 problems

    Hi,

         we have planed for using the AD7190 ADC  for weighing. while testing we have face some problems. we are choosing 100/200hz data rate,gain=8,sinc4 filter. we are using SPI of  PIC16F877A microcontroller.

    We have done the following settings in our…
