• 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 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！

  • 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 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,
