• AD7194: Voltage bias to thermocouple

    Hello,

    I working on Thermocouple amplifier based on AD7194.

    - 3 chanels, S-type, PT100 CJ compensation.

    - ADR421 reference, 2.5V

    - 5V power supply

    Could I use TC voltage biasing according picture below?

  • AD7194 0-10V (pseudo)-differential input

    I'm trying to build an add-on board to a data acquisition board, which has the following input filter:

    I want to attach a secondary board that can have an input between 0 - 10V. The AD7194 has a 5V reference connected to it and therefore the 0-10V…

  • 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,

  • 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…

  • 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,…

  • 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…

  • 关于AD7194请帮忙分析下，谢谢！

    AD7194BCPZ芯片使用问题 ，我们打样了2块PCB板子，1块板子上有4片AD7194。目前2块板子上都是只有1个片子工作正常。板子上 2片AD7194挂1组SPI总线与MCU通信
    ，AD7194用的片内时钟。

    有问题的AD7194片子现象：

    1、SPI总写读写时序正常。

    2、通过通信寄存器读取ID寄存器返回的数据都是0xA0,读取ADC转换结果的寄存器数据全是0X00000000000，操作其他寄存器返回的数据正常。

    3、通过配置寄存器使用片内时钟，并输出片内时钟，用示波器测得的频率为7…
