• AD7194 Odd Behavior

    I'm confused by the behavior of my AD7194.

    I have the following configuration:
    - Channel to be measured at AIN1
    - 2.5V reference voltage at AIN9
    - 4.1V reference voltage at REFIN1(+)
    - GND at REFIN1(-)

    I have this configuration due to a separate upstream…

  • interfacing multiple ad7194

    helloo all,

    iam interfacing two AD7194 adc's to a single microcontroller using spi interface. And i use the same chip select pin from the microcontroller to select the two adc's using a MUX. And the steps for reading the data from the adc inc…

  • AD7194输入问题

    ADI专家，你好！

    我现在用AD7194+PT100铂电阻(四线制，1mA恒流)做温度采集，精度0.1℃，输入的电压范围是60mV~120mV，如果用7194的UNBUF模式，是不是输入阻抗太小，影响精度？是在AD7194前端还需要做一级放大，还是直接用7194中的增益，哪种更好？如果前级需加放大，麻烦推荐一款运放。谢谢！

  • AD7194地线问题

    请问ADI专家，AD7194的模拟地和数字地最好应在什么位置接入系统地？

  • Recommended update over AD7194

    I'm selecting an ADC for an application measuring seven resistive load cells, using an amplifier gain of 128, in sequence (aiming for an individual rate of about 420 Hz, for a combined sample rate of 60 Hz). I've been using an AD7194 for prototyping,…

  • Looking for AD7194 No-Os driver

    Hi, 

    I have been searching AD7194 No-Os driver to interface it with my MCU...Unfortunately, I did not get anything in its name...So, could someone point me where it is?

    Thanks,

  • OS for AD7194 Evaluation board

    Hi,

    I tried to use AD7194 Evaluation board with 62bits Windoews7, but the driver of evaluation board can not be installed.

    What kind of OS can be used for this evaluation board?

    Best regards,

  • AD7194 data register read problem

    Hi,

       I am using AD7194 in pseudo differential mode.I have used AIN1 channel.

    I have set configuration register as 04B018 and mode register as 280060.I have given a .5 V voltage input to AIN1. But when I try to read the data register ,I am getting ffff…

  • Ad7194 over voltage at input

    I accidentally gave over voltage at one of the input pins of the adc.But some channels of the chip respond correctly when I do a configuration register read and some returns 0xffffff. And the ic respond correctly when i read ID register.How i know the…

  • AD7194 measured value double expected value

    I am using an AD7194 as slave to an Atmel Atmega128 uC. I have a 4.096V reference tied to REFIN1(+), and GND tied to REFIN1(-)

    After powerup, I send the AD a reset: 0xFFFFFFFFFF

    Then I send this to the config register: 0x00E900

    That should set ref to…
